Abstract

Reflectivity, luminescence and excitation spectra as well as nanosecond luminescence decay kinetics were measured for PbSO₄ and PbCO₃ (as well as CaCO₃:Pb) by photon excitation between 4 and 35 eV. These measurements were compared to those of PbWO₄ in order to establish the role of lead states in these compounds, which are potentially interesting as scintillators. New luminescence bands were observed in PbSO₄ at 340 nm and in PbCO₃ at 320 nm. Luminescence properties are discussed assuming the lead parentage of electronic states in the vicinity of the forbidden energy bandgap
