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.
