Thermoluminescence of Light and X-Ray Irradiated Semiconductor-Doped Glasses

Abstract

Thermoluminescence has been observed in light and X-ray irradiated CdS-doped glasses and light irradiated CdSSe-doped glasses. The intensity of thermoluminescence was measured as a function of irradiation intensity and irradiation time. Applicability of CdS-doped glasses as a material for a radiation dosimeter was discussed.

Thermoluminescence and absorption spectra of CdSe quantum dot-doped glass irradiated by X-rays

“…In the case of light irradiation, a two-step excitation process seems more realistic (the intensity of thermal luminescence is proportional to J 2 , where J is the irradiation intensity) [1,3]. At the first step, the electrons excited by ionizing radiation go from the valence to the conduction band of nanoparticles.…”

“…So far there are few publications concerning CdSSe [1] and CdS [2][3][4][5][6][7] nanocrystals only. However, a number of problems have arisen by this time that requires a prompt solution both from fundamental and applied points of view.…”

Thermoluminescence in semiconductor-doped glasses

“…Thermoluminescence is observed in light irradiated CdS-doped glasses [3,4]. Effect of light irradiation was examined using a fluorescent lamp.…”

“…Thermoluminescence is also observed in X-ray irradiated CdS-doped glass [4]. Here, we report the thermoluminescence of X-ray irradiated CdS-doped glass, and it was compared with that of phosphor for commercial radiation dosimeter.…”

Thermoluminescence and induced absorption in X-ray-irradiated CdS-doped glasses

“…In previous articles, we reported thermoluminescence of laser-and X-ray-irradiated CdS-doped glasses above room temperature [4,5] and the induced absorption in X-ray-irradiated CdS-doped glass [6]. However, relation between the induced absorption and thermoluminescence remained unclear.…”
