Hole transport model
For this type of material, the earliest model was the hole transport model proposed by Matsuzawa et al. in the SrAl2O4:Eu, Dy system. Based on this model, Matsuzawa believes that in the long afterglow materials SrAl2O4:Eu, Dy, Eu is the electron capture... 查看详情

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... 查看详情

1. Selection of resin:
Had better choose powdery form resin, with the resin with melting index a bit taller relatively.
2. Selection of luminous pigments:
Type C or D is more effective, and the particle size is too large or too small for dispersion.
3. Selection of lubricant:... 查看详情
