RECRYSTALLIZATION OF ACTIVATED RARE-EARTH OXYHALIDE PHOSPHORS |
摘要 |
A method for the recrystallization of activated rare-earth oxyhalide phosphors is disclosed. The method comprises recrystallizing the phosphor by firing a phosphor-flux mixture in an inert atmosphere. The phosphor-flux is substantially homogeneous and the flux contains substantially dehydrated magnesium halide. One particularly preferred phosphor made by the method is a lanthanum oxychloride phosphor coactivated with bismuth and ytterbium. This phosphor made by the present method has high speed and low afterglow. |
