Enhancement of Photoluminescence and Color Purity of
: CaTiO3 Phosphor by Eu Doping
High color purity red phosphors of
Eu and TiO3 1−2x
(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 TiO into Li+ : CaTiO3 .
The Eu3+ doping increases the emission probability from 5D0 state, increases photoluminescence intensity by 1.6 times, increases color purity to 92.1%, and shortens the decay time. With increasing Li+
and Eu3+ content, the color coordinates approach the ideal red chromaticity values, coming closer than commercial Li+ red phosphor.
