摘要：
Photoluminescence properties were improved in CaTiO3:Pr3+ phosphor by substitution of Ba and Sr for Ca to a large extent of Ba (0-20%) and Sr (0-45%) fractions. Red emission intensity at 612 nm was greatly enhanced. It achieved its largest value in Ca0.7Sr0.3TiO3:Pr3+ sample, higher by 192% than CaTiO3:Pr3+. Enhancement of red emission in Ba and Sr added CaTiO3:Pr3+ is inferred to originate from improvement of Pr-3+ 4f5d capture probability to electrons in the host conduction band and charge transfer state, which are lowered by Ba and Sr addition.
