Abstract
The main ingredient in Photoluminescent Liquid Crystal Display (PLLCD) is near UV excited phosphor for illumination. It is the need of PLLCD device to develop a phosphors that can absorbs excitation energy in the near UV region. To meet these requirement of PLLCD device , synthesis and photoluminescence characteristics of CaSO4:Eu2+ , Sr5(PO4)3Cl:Eu2+, (Ba, Sr) SiO4:Eu2+, (Y,Bi)2O3:Eu3+ is reported here. CaSO4:Eu2+ emits radiation in the near UV region at 388nm. This near UV energy is absorbed by (1) Sr5(PO4)3Cl:Eu2+ to emit blue radiation at 446 nm .( 2 ) (Ba, Sr) SiO4:Eu2+ to emit green light at 537nm and ( 3) (Y,Bi)2O3:Eu3+ to give red light emission at 611 nm. It found that these phosphors are promising RGB (Red,Green, Blue) emitters for fabrication of PLLCD device.
