摘要：

A series of Pr3+-doped CaSnO3, SrSnO3 and Ca2SnO4 samples were prepared by a conventional high temperature solid-state reaction route. All samples were characterized by powder X-ray diffraction (XRD) analysis, photoluminescence (PL), photoluminescence thermal quenching (TQ) and fluorescence lifetime (FL) measurements. Moreover, luminous efficacies (LE) and color points according to the CIE 1931 color space diagram were calculated and discussed. The incorporation of Pr3+ ions into CaSnO3 and SrSnO3 host materials results in intense white luminescence, which originates from the mixture of green, orange and red emissions. Pr3+-doped Ca2SnO4 phosphor emits intense red light upon excitation. Temperature dependent luminescence lifetime measurements of SrSnO3:Pr3+ phosphor showed abnormalities near 180 and 260 K, which confirm the existence of a low temperature structural phase transitions in SrSnO3.
