Phototransferred Thermoluminescence and Exo-Emission in Alpha Alumina
a-Al2O3, irradiated by ionising radiation and submitted to UV illumination (?>250 nm), presents a phototransfer phenomenon that is characterised by thermoluminescence (TL) and by thermostimulated exoelectronic emission (TSEE). The TL and the TSEE glow curves of a-alumina from -196 to 700 oC are compared, to parallel one phototransfer observation with another and to draw various conclusions concerning the stability of the traps involved in dosimetric applications.
