via

a high temperature solid state reaction

the crystal structure of the obtained phosphors was characterized by XRD technique. The results of photoluminescence spectra indicated that the phosphors could be effectively excited by 380 and 274 nm and evoked downconverion emissions. Temperature quenching behavior was observed in the phosphors under 380 nm excitation. The influence of host on the characteristic temperature of fluorescence emission was studied

and it was found that the host greatly affected the characteristic temperature and that KLa(MoO
