Abstract
PURPOSE: To obtain a fluophor giving highly efficient luminescence under an excitation of X-ray, etc., having outstanding afterglow characteristics, and useful as fluophor films for radiation-sensitive image convertors, by activation, with divalent europium, of a base consisting of a composite halide made up of a potassium halide and an alkaline earth metal halide.
CONSTITUTION: There kinds of raw materials: (a) a potassium halide of formula KX (X is chlorine or bromine), (b) an alkaline earth metal halide of formula MeX'2 (Me is barium, strontium, or calcium; X' chlorine or bromine), and (c) a europium halide of formula EuX"3 (X" is chlorine, bromine, or fluorine), europiumoxide, etc., are so mixed stoichiometrically as to satisfy the composition formula (x and y are determined under conditions 0.5≤x≤3 and 0.001≤y≤0.2). The mixture is subjected to calcination at 600W1,000°C in a weakly reducing atmosphere, thus obtaining the objective fluophor.
