LUMINESCENCE OF KI UNDER X-RAY IRRADIATION

· Nuovo Cimento (Italy) Divided into Nuovo Cimento A and Nuovo Cimento B
The x-ray induced luminescence of KI was investigated at 200 to 600 nm, at -180 to 80 deg C. Changes in the intensity and spectral distribution of the luminescence are studied, as a function of the irradiation time, and under the infiuence of plastic deformation, additive coloration, and heat treatments. Heating in vacuum induces a 400-nm emission band, which is practically absent in as received'' cnystals; plastic deformation and heating in air enhances the 515- nm emission band, otherwise very weak. The depend ence of intensity on the x-ray dose and the conscquences of various heat treatments suggest that the 515-nm emission is due to a color center associated with an oxygen impurity. (auth)
