“…KCl:Eu 2+ , Ce 3+ ) acts as a potential thermoluminescence (TL) and OSL dosimeter due to its high sensitivity to ionizing radiation because of the enhanced intensity of TSL (thermally stimulated luminescence) and OSL as against single doping (i.e. KCl:Eu 2+ and KCl:Ce 3+ ) [4]. It has been also reported that the occurrence of different states of dopants Eu 2+ due to the heat treatment influences the absorption and fluorescence optical properties for KCl-KBr-RbBr:Eu 2+ crystals [5].…”

Analyzing the data on bleaching with the F-light at the excitation bandpass 5 or 20 nm, it was found that the absorption spectrum of KCl:Eu2+ (0.1 mol%) single crystals exposed to X-ray has a peak due to Fz-centre within the wavelength 20 nm near F-centre peak. Deforming the X-ray-irradiated KCl:Eu2+ (0.02 mol%) single crystal by the compression at 100 𝜇m min−1, a new peak is observed around 330 K on the thermoluminescence (TL) glow curve. Its color centre has a new energy band near F-band, which is based on the F- and thermal-bleaching effects of the compressed crystal.
