A bracelet that can emit luminescence, what if the luminous is not as bright as it used to be

If the glow-in-the-dark effect of the glow-in-the-dark bracelet becomes weaker, there may be several reasons:

1.Luminescent material loss: The glow-in-the-dark effect of the luminous bracelet is emitted by the luminescent substance. If the fluorescent substance has been depleted, then the glow-in-the-dark effect will be weakened.

2.Light source problems: If there is a problem with the band's built-in light source, such as a damaged light source or a reduced brightness of the light source, it will also cause the glow-in-the-dark effect to be weakened.

3.Low battery: If the battery of the bracelet is too low, it may cause the brightness of the light source to decrease, which will affect the glow-in-the-dark effect.

4.Fluorescent substance is cleaned: If fluorescent material is cleaned, it may cause the glow-in-the-dark effect to be diminished.

Here are some possible solutions:

1.Replacement of fluorescent substances: If the fluorescent species has been depleted, consider replacing the fluorescent substance.

2.Replace the battery: If the battery is too low, you can replace the battery to improve the brightness of the light source.

3.Replace the light source: If the light source is damaged or the brightness is reduced, consider replacing the light source.

4.Avoid cleaning: In order to avoid fluorescent substances being cleaned, you can try to avoid the bracelet being cleaned or coming into contact with other cleaning agents.

If none of the above methods solve the problem, it is recommended to contact the manufacturer or seller for further consultation or repair.

The glow-in-the-dark bracelet is a silicone raw material with luminous powder added in the middle.

If you don't have a light to shine on, if you don't absorb light, it won't shine.

Of course, the light absorption and luminescence of luminous powder will also decline with the change of time, so if it takes a long time, it is possible that the brightness is not as good as before, I hope it will help you!

If it's radioluminescent, just buy another one;

If it is fluorescent, natural light can be restored.

You can freeze it in the refrigerator for a few hours, take it out and break it again, and it will be bright.

Look at what light you are in, the light is too weak to absorb the light yesterday.

The excitation wavelength of long-acting luminous powder is generally 520 (nm).

Long-lasting luminous powder product characteristics:

Yaodexing Technology's long-term luminous powder has a luminous time of more than 10 times that of short-acting luminous powder, with good weather resistance, and can be used both indoors and outdoors.

There are two main contraindications for the use of long-term luminous powder of Yaodexing Technology: 1. Avoid contact with water (except for waterproof treatment); 2. Avoid direct contact with metal (easy to blacken); There is no such contraindication for short-acting glow-in-the-dark powder.

The specific gravity of Yaodexing Technology's long-term luminous powder is that the material is alumina, strontium carbonate and rare earth elements, and the material itself is non-toxic and harmless, does not contain radioactive substances, and has a long light absorption time and a long light release time.

The luminosity inside is ineffective. It is best not to wear glow-in-the-dark jewelry, most of which have radiation.

Let it dry in the sun for a while.

In this case, you can try to keep the watch illuminated in the sun or light for a period of time, and the glow-in-the-dark effect will be enhanced.

Luminous watches are made with luminous powder applied to the dial numerals and hands, so that the time can be seen at night or in the dark.

Luminous powder is based on powdered zinc sulfide, which itself does not emit light, but has phosphorescent characteristics, that is, it is excited after sunlight or light irradiation, and will continue to emit light for a certain time, but the time is shorter.

Night light also needs to be lit to be lit, so try to shine more lights.

Go fix it or give it to me hee hee or buy more or throw it away (if you don't give me a share, I'll break up with you!!) —

...There's no way to fix this, you go and show the boss to see if there's anything you can do.

That is the fluorescent solution, the preparation of the reagent: AR dibutyl phthalate, AR hydrogen peroxide 30%, CPPO (bioxalate), fluorescent dyes (such as romindane B), sodium carbonate (or sodium acetate, sodium salicylate, sodium salt of organic acids).

1.Prepare 30 ml of dibutyl phthalate into a beaker.

2.Add 1-2 g of CPPo3 to 30 ml of dibutyl phthalatePlace the beaker in a hot water bath and wait for the CPPO in dibutyl phthalate to dissolve.

4.Scoop a small amount of fluorescent dye with the toothpick tip and mix with the sodium carbonate (catalyst) of the two toothpick heads.

5.When the CPPO in step 3 is almost dissolved, pour 10 ml of hydrogen peroxide into a beaker and continue the water bath.

6.After the water bath, add the powder mixture from step 4, shake, and continue the water bath for a short while, you can see that the upper liquid turns milky white.

7.Add catalyst sodium carbonate to your desired brightness.

You see, it's troublesome, so I suggest you buy a new one.

It's useless, the raw materials in the fluorescent bracelet are disposable, and they can't be recovered after they are exhausted.

The fluorescent bracelet contains hydrogen peroxide, diglycolate oxalate (CPPO), and fluorescent dyes. Hydrogen peroxide first reacts with oxalate diesters to form a 1,2-dioxetanedione intermediate, which breaks down into carbon dioxide, and in the process hands over the released energy to the fluorescent dye. The fluorochrome then converts the energy gained into light energy, and different fluorochromes emit different colors of light.

After the fluorescent bracelet is not lit, the hydrogen peroxide and dioxalate in it have been exhausted, and the fluorescent dye will not be consumed during the luminescence process. So the fluorochrome is still in there, but it's useless to take this thing out.

It can't be used. Throw it away, chemicals.

During the day, when there is sun, put more sunshine in the sun, and only at night can there be electricity.

The luminescence phenomenon of matter is generally divided into two categories: one is the heat of the substance, which produces heat radiation and emits light, and the other is the process of the substance being stimulated to absorb energy and transition to the excited state (non-stable state) and then return to the ground state, releasing energy in the form of light. The use of fluorescent coatings on watches makes use of the second type of principle, that is, the luminescence of luminescent materials when stimulated.

Types of luminous materials:

Traditional fluorescent coating materials can be divided into two types: self-luminous and phosphorescent. Self-luminous fluorescent agents mostly rely on the release of rays from trace radioactive substances carried by themselves to excite fluorescent agents. The light-storing fluorescent agent basically does not contain radioactive substances, but it needs to absorb and reserve sufficient intensity of external light in advance to jump its own electrons from a low energy level to a high energy level and store it.

When the surrounding environment is dark, it gradually and slowly releases the absorbed energy, and the electrons transition from high to low energy levels, and the fluorescent agent begins to emit light. Since the light storage type itself does not carry the ray excitation material, the afterglow durability is temporarily inferior to that of the self-luminous type.

The watch is not lit at night, which means that it has not been irradiated by the sun during the day, and it is indeed energy, and the luminous watch must be irradiated by the sun to absorb energy and glow at night.

If the luminous coating does not absorb light during the day, then there is not enough energy to emit luminous light, you can use a flashlight to illuminate the dial at close range for about 30 seconds, and then observe the glow-in-the-dark effect.

Go to a sunny place during the day and shine at night.

However, some glow-in-the-dark watches are fake, just have a fluorescent coating and never shine light.

Why doesn't the watch's glow-in-the-dark light turn on? Most of this is the reason.

Throw it away, buy a new one. And you have to buy a high-end product.

There is no way, the general fluorescence can last for a few hours, it can't last for a night at all, there is only a faint light in the second half of the night, it is difficult to see clearly, if you want to see clearly in the middle of the night, buy the self-luminous one, but there is radiation and the life is short, it will not be lit in a few years, or use the kind with LED lights.

This is just the difference in the light-absorbing ability of different colored fluorescent substances, green light is the strongest, that is, the brightest.

One is that it takes too long.

There are also requirements for light, or the fluorescence dose contained in it is different.

It's very simple, and it will slowly fade after a long time.
