Application of luminescent powder in printing paste

The preparation and application methods of luminous printing paste described in this paper are for reference only, and corresponding adjustments should be made in practical application. Select medium-sized or alkaline transparent printing paste and D-type or S-type luminescent pigment with the weight ratio of 20-50%, and mix them evenly. Adjust the viscosity with the corresponding diluent. Before printing luminescent printing paste, you should first lay a layer of white background. The following transparent printing pastes are available for selection. Nylon printing paste Advanced...

The development of blue long-lasting phosphorescent materials for fibers

The main raw material for preparing blue light night glow fibers is the rare earth long-lasting phosphorescent material that can emit blue light. The research fields of blue light long-lasting phosphorescent materials include the metal sulfide system, the aluminum oxide system, and the silicate system. In 1866, French chemist Theodore Sidot prepared ZnS-based sulfide phosphorescent materials, which belong to the first generation of long-lasting phosphorescent materials. Since the 1920s, people have begun to develop blue light sulfide system long-lasting...
