摘要
在25 ~ 300 K范围内研究了pb2 +在羟基磷灰石CaPb x (PO(OH) 2中衰变的温度依赖性。研究表明，光致发光过程主要受亚稳态3p0水平的控制。极低温时的宽发射带归因于3p1s0，高温时的宽发射带归因于3p1s0。
Kinetics of Pb2+-doped calcium hydroxyapatites fluorescence
Temperature dependence of Pb 2+ decays in the hydroxyapatites CaPb x (PO(OH) 2 has been studied between 25 and 300 K. It has been showed that the process of photoluminescence is mainly controlled by the metastable 3 P 0 level. The broad emission band at very low temperature is attributed to 3 P 0 1 S 0 and at 3 P 1 1 S 0 at higher temperature.
