Temperature dependence of Pb2+ decays in the hydroxyapatites CaPbx(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.
