Abstract Photoluminescence (PL) experiments have been carried out in glasses from the ZnO-CdO-SiO2 system. The glasses exhibit broad bands in the PL spectra centered between 540 and 560 nm for emissions and at about 250 nm for excitations. Decay time curves for the different glass samples appear, within experimental errors, quite similar. The curves are not a simple exponential and have been discomposed as a sum of three exponentials with lifetime components of about 0.025, 0.1, and 0.52 ms. The results seem to indicate that luminescence is dominated by short ordering, nuclei and/or crystalline centers.
