Abstract
Single phase of Ca1−xMo1−ySiyO4:Eux3+ (0.18⩽x⩽0.26, 0⩽y⩽0.04) was synthesized by solid-state method. The photoluminescence investigation indicated that Ca1−xMoO4:Eux3+ (0.18⩽x⩽0.26) could be effectively excited by 393 and 464 nm, and it exhibited an intense red emission at 615 nm. The introduction of Si4+ ions did not change the position of the peaks but strongly enhanced the emission intensity of Eu3+ under 393 and 464 nm excitations and showed very good color purity. The emission intensity of optimal Ca0.8Mo0.98Si0.02O4:Eu0.23+ sample (excited by 393 nm) was about 5.5 times higher than that of the phosphor Y2O2S:0.05Eu3+. So this phosphor could be nicely suitable for the application of the UV LED chips.
