Abstract
PURPOSE: To obtain a fluorescent substance emitting green color, suitable for index tubes, having improved emission efficiency and brightness, and prepared by adding NaCl and KCl to a lanthanium thiogallate activated with cerium as a raw material, and calcining the mixture.
CONSTITUTION: 2wt% Sodium chloride or pottasium chloride or both are added to a raw material of a fluorescent substance consisting of lanthanium thiogallate activated with cerium essentially. The resultant mixture is then calcined to give the aimed fluorescent substance of short afterglow, exhibiting green emission with excitation of electronic rays and ultraviolet rays, and having a greatly improved light output.
USE: A flying spot tube etc.
