What is traditional Zinc Sulphide pigment? Some of the first phosphors to be developed were inorganic zinc sulphide compounds. (German submarine commanders during World War I reportedly rubbed these compounds on their hands to read documents during blackout conditions.) These phosphors typically absorb energy from deep blue and ultraviolet light and emit it as yellow-green light.This is useful in that the peak spectral distribution of the emitted light roughly coincides with the peak spectral sensitivity of the human visual system...
Phosphor is a special crystal structure luminescent material, which has a strong absorbance - STORING - luminous ability, when illuminated by natural light and the light, that part of the light energy is absorbed and stored, and then in the form of visible light in the dark Slowly release the luminescent material after five minutes after the light in the dark can automatically light for more than 12 hours of light absorption process can be repeated countless times glowing,...
With the photoluminescent pigment in the handicraft industry and the toy industry applications, the use of innovative design, reasonable selection, fine production, in order to a better understanding of the relevant knowledge, and we explain below small explain luminous powder in industry Application: Now more and more customers start using photoluminescent pigment to change the performance of their products, but many of its own characteristics photoluminescent pigment is most customers do not know, for example, there are a variety of...
