CAMERON BANDS IN THERMOLUMINESCENCE OF CO DOPED SOLID AR.

Abstract

The emission spectra of CO doped solid Ar were obtained in the temperature range 5-30K during the thermoluminescence and cathodoluminescence measurements using the low energy electron excitation. The changes of the bands shape due to variation in the sample growth conditions were studied. Thermally activated emission of the Cameron bands was observed for the first time. Applying a deconvolution of the thermoluminescence glow curves, parameters of single glow peaks were determined. Within the Randall-Wilkins approximation, solid argon electron traps depths were obtained by the numerical fitting of the glow curves.
