Abstract

Temperature dependence of Pb²⁺ 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 ³P₀ level. The broad emission band at very low temperature is attributed to ³P₀ ¹S₀ and at ³P₁ ¹S₀ at higher temperature.
