Research paper thumbnail of Synthesis and characterization of phosphors doped with various rare earths

T... more A blue emission powder phosphor , Sr 2 CeO 4 was prepared using solid-state reaction technique. The powder fired at 1100 0 C for 3 hours gave good luminescence yield. The emission peak of this phosphor is at 470 nm. To use this phosphor in a tricolor lamp effectively, studies have been carried out to see the effect of rare earth dopants on the luminescence spectra of this phosphor. The effect of the dopants on phosphor efficiency has been evaluated and the effect of using these dopants and material characterization of these phosphors using optical and structural techniques are discussed in this paper.
