Photon yields and decay times of cross luminescence in ionic crystals
The authors report on the scintillation properties of the ternary inorganic crystals KMgF/sub 3/, KYF/sub 4/:Rb, K/sub 2/YF/sub 5/, KLuF/sub 4/, RbMgF/sub 3/, KZnF/sub 3/, BaTm/sub 2/F/sub 8/, LiYF/sub 4/:Nd, and BaF/sub 2/:Rb. The scintillation light output of these crystals was estimated from the X-ray-induced emission spectra. Optical absorption spectra and decay time spectra were also measured and are presented. The first four crystals produced cross-luminescence (CL) with a decay time of about 1.5 ns. CL was not observed for the other crystals. >
Scintillation properties of possible cross-luminescence materials
Abstract Employing X-ray and gamma-ray excitation, we studied the scintillation properties of KMgF 3 , KYF 4 :Rb, K 2 YF 5 , KLuF 4 , RbMgF 3 , KZnF 3 and BaTm 2 F 8 crystals. The first four crystals produce intrinsic cross-luminescence (CL) with a decay time of about 1.5 ns. Intrinsic CL was not observed for the other crystals. Emission spectra, results of decay time measurements, and estimates for the absolute light yield are presented.
