Natural and synthetic samples of hardystonite, hydrozincite, calcite and pyromorphite were investigated by laser-induced time-resolved luminescence spectroscopy at 50 K to ambient temperatures. Luminescent bands of Pb2+ can be resolved from similar bands caused by Ce3+ and Eu2+ by a combination of diagnostic differences in excitation spectra and lifetimes of luminescence as a function of temperature. The results indicate that Pb2+ is a more common luminescent activator in minerals than hitherto suspected.
