摘要
Red-emitting phosphors, (La1-xCax)OCl:y%Eu3+ (0 <= x <= 0.17, 1 <= y <= 5), were synthesized in a single-phase form by a liquid-phase method and photoluminescence properties were characterized. The excitation peak intensity of the phosphor was increased with Ca2+ doping into the LaOCl lattice, corresponding to the successful enhancement of the emission intensity. The maximum emission intensity was obtained for (La1-xCax)OCl:y%Eu3+, where it was 63% of that of a commercial Y2O3:Eu3+ phosphor.
