| titleOfInvention | Red light phosphor and multilayer photo-transforming film |
| abstract | The present invention relates to a red light phosphor, which is based on sulfide and activating agent containing rare earth strontium or hafnium. It is characterized by that the aforementioned materials are a fluorine-sulfur oxide containing lanthanum-yttrium-zirconium and/or hafnium with its stoichiometric formula as (La 1-x-y-z Y x A y Me z +4 O) 2 S 1 (F −1 ) 2z , and activating agent based on A=(TR +3 =Σ Eu, Sm, Gd, Tb)+(TR +4 ═Pr +4 ), in which Me +4 =Zr +4 and/or Hf +4 . Compared with standard materials, the luminous intensity of the phosphor according to the present invention is increased to 1.6-2.4 times. Further, the red light phosphor according to the present invention has a mean diameter of d 50 ≈0.6 μm. The present invention also discloses a multilayer photo-transforming film, in which the three-layer agro-film is filled with phosphor. The agro-film is based on polythene and its derivatives and added with photostabilizer. |
