Talking about the difference between luminous powder and luminous powder

First, the difference in appearance

Many people usually confuse phosphors with luminous powder, even called phosphors. As everyone knows, the difference is very big. So what is phosphor and what is luminous powder?

1. The most obvious difference is that after a few minutes of illumination, in a dark environment, the luminous powder will illuminate by itself, and the phosphor will not emit light by itself. This is the most obvious difference.

2. From the appearance point of view, phosphors or fluorescent products will look brighter in slightly light, while luminous powder will be pale and inconspicuous.

3. From the application point of view, phosphors are more common in clothing, plastic products, traffic signs, etc. Luminous powder is more common in night signs, where light is weaker for easy observation.

Second, the detailed introduction

Luminous powder is usually divided into photo-energy storage luminous powder and radioactive luminous powder. Photo-storage luminous powder is a fluorescent powder that is stored in natural light, sunlight, ultraviolet light, etc., and then stored in a fluorescent manner, and then slowly released in a fluorescent manner, so at night or in the dark. , still can see the light, lasting for hours to ten hours. The luminous powder of Shenzhen Xingsheng Pigment Co., Ltd. is a luminous energy-saving environmentally friendly luminous powder. It does not have radioactivity and has no direct harm to the human body. It can be used with confidence.

Phosphors, usually referred to as fluorescent fluorescent dyes, are some of the compounds with special structures. The structural features are mainly as follows:

(1) The molecule contains a group that emits fluorescence, such as a carbonyl group, a nitrogen-nitrogen double bond, a carbon-nitrogen double bond, and the like.

(2) The molecule contains a color-assisting group. A coercive group red shifts the spectrum and increases fluorescence efficiency.

Such as primary amino groups, secondary amino groups, hydroxyl groups, ether bonds, amide groups and the like. π bond (3), a conjugated π bond containing a rigid planar structure in the molecule. The greater the in-molecular conjugate system, the stronger the planarity and the higher the fluorescence intensity. Some factors that increase the degree of conjugation increase the fluorescence efficiency and shift the fluorescence wavelength toward the long wavelength. Very bright colors in daylight or visible light. Can't shine in the dark.
