Advanced materials with unique optical and thermal properties for a new generation of solid state light sources for replacement of conventional phosphors (composite materials, carbon-based nanostructures, transparent oxides)
In this area, the technologies of new inorganic phosphors getting based on crystalline materials and glass ceramics are being developed.
Images of the surface of a sample of heat resisting phosphor: SiO2 - PbF2 - PbO(Pb3O4) - AlF3 (40:30:20:10), obtained at a temperature of 600 0С
A) The mass concentration of the phosphor in a mixture 80%
B) The mass concentration of the phosphor in a mixture 9.1%
