摘要：

We have observed that the thermal quenching of light emission from (La,Ce)PO4:Tb is greatly improved by substituting borate for a small part of phosphate or doping with thorium. The emission intensity remains almost constant in the temperature range from 20 to 350-degrees-C. The reason for the improvement could possibly be attributed to all of cerium becoming trivalent because of the presence of borate or thorium.
