We analyzed the time-resolved luminescence properties of α-Al 2 O 3 under heavy ion irradiations in the vacuum ultraviolet (VUV) wavelength region. A luminescence band at approximately 170 nm, at which a luminescence band was observed under VUV irra

The decay of the luminescence due to self-trapped excitons (STE) induced by ion irradiation of a ${\mathrm{BaF}}_{2}$ single crystal has been measured. It is shown that the decay of STE created by ion irradiation is much faster than those created by

The visible scintillation around 690 nm from Desmarquest AF995R, which is used for real-time beam monitoring, was investigated on steady state γ-radiolysis at room and low temperatures. The temperature dependence of the scintillation intensity indic

Ion-irradiated BaF2 and CsCl showed LET-dependent decrease in the decay times of both the Auger-free luminescence (AFL) and self-trapped exciton (STE). A decrease in temperature makes the decay of STE fast. These LET and temperature effect are explai
