Abstract
This paper investigates the structural and optical properties of Eu3+ doped LaVO4 phosphor via co-doping of Li+ and Ca2+ ions. The unit cell volume and particles size vary with Li+ and Ca2+ ions. The Eu3+ doped phosphor emits intense red color at 613 nm due to Eu3+ ion on excitation with 266, 355 and 394 nm. The photoluminescence intensity of Eu3+ doped phosphor is enhanced up to 2.1 and 4.5 times via co-doping of Li+ and Ca2+ ions, respectively. Therefore, the Eu3+, Li+, Ca2+ co-doped LaVO4 phosphor may be suitable candidate for the development of display devices and white light emitting diodes.
