Why do fluorescent stickers glow by themselves

Why does the fluorescent sticker glow by itself? Because the fluorescent sticker contains fluorescent powder! Phosphors (commonly known as luminous powder) are usually divided into two types: light-induced energy storage luminous powder and radioactive luminous powder. Light-induced energy storage luminous powder is a phosphor that stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc., and slowly releases it in the form of fluorescence after stopping the light irradiation. 

So at night or in the dark, you can still see the light, which lasts from several hours to ten hours. Radioactive glow-in-the-dark powders are mixed with radioactive substances in the fluorescent powder, and the radiation emitted by the radioactive substances is used to excite the fluorescent powder to emit light. This kind of glow-in-the-dark powder has a long light-emitting time, but has a small application range such as toxic, harmful and environmental pollution.

Luminous paper is coated with fluorescent materials, and there are two principles of light emission:

One is to use natural minerals that can store light, and when there is outside light, it absorbs a part of the light energy and stores it. When the outside world is dark, it will naturally release part of the stored light energy, thus producing a luminous effect.

The other is to use non-woven fabric as the raw material. After being irradiated by the purple light, it produces a luminous effect, because the tool must be used as the purple light. Usually the luminous principle we call is the first.

The fluorescent substance used now is mainly white powder of zinc sulfide or copper sulfide. They will absorb a small amount of energy when illuminated by light, and when they leave the light source, they will emit a faint fluorescence, which is green.

People often add a very small amount of activator to the above-mentioned fluorescent substances: adding 1/10,000 of copper chloride and copper nitrate can enhance the brightness; adding substances such as manganese chloride or silver nitrate will adapt the fluorescent materials to emit different colors of light.

Rear gear fluorescent sticker refers to a car sticker that is affixed to the rear glass of a car and emits light fluorescence at night. This kind of car sticker is also quite suitable as a car's personalized decoration, but if you stick this rear bumper fluorescent sticker to drive at night, it is prone to accidents.

The backshield fluorescent sticker must first absorb light, and then it can display the light effect in the dark environment, daylight and night light. The back block fluorescent stickers are beautiful and unfading. The fluorescent stickers come with double-sided stickers on any position you like. It has a good decorative effect during the day and a fluorescent effect at night. More able to decorate your home.
