Popis:	Thermally stimulated luminescence (TSL) of aluminoborosilicate glass doped with CdSe nanoparticles (28 and 47 A) has been studied after exposure to ionizing radiation; the intense TSL peaks were observed at temperatures 150 and 85 °C, respectively. The optical absorption spectra, as well as TSL of the irradiated samples containing CuBr nanoparticles (44 A) were also measured. In the case of CuBr, TSL was observed neither before nor after irradiation. The dependence of TSL intensity on irradiation time indicates that glass activated by CdSe nanoparticles shows promise as a dosimetric material.
