Abstract

High color purity red phosphors of Ca 1-3/2xEu xTiO 3 and Ca 1-2xEu xLi xTiO 3 (0 < x ≤ 0.3) are synthesized via a solid-state reaction method. The red emission photoluminescence intensity and color purity are enhanced by the incorporation of Li + into CaTiO 3:Eu 3+. The Li + doping increases the emission probability from 5D 0 state, increases photoluminescence intensity by 1.6 times, increases color purity to 92.1%, and shortens the decay time. With increasing Eu 3+ and Li + content, the color coordinates approach the ideal red chromaticity values, coming closer than commercial Y 2O 2S:Eu 3+ red phosphor.
