Abstract
PURPOSE: The titled fluorescent substance giving a fluorescent membrane with high brightness and excellent contrast, which comprises a red-luminescent yttrium oxysulfide activated with europium and a filter material prepared by coating In2S3 surface with a composite sulfate of Na and Cs.
CONSTITUTION: The purpose Y2O2S/Eu fluorescent substance coated with indium sulfide and sodium cesium sulfate is prepared by sticking In2O3 on the surface of a red-luminescent Y2O2S/Eu fluorescent substance and mixing S, Na2CO3 and Cs2CO3, followed by calcination. The filter material in the fluorescent substance is prepared by coating In2S3 surface with a composite sulfate of Na and Cs. It is preferable to specify amounts of the raw materials such that a wt. ratio of the total of Na and Cs in the composite sulfate to In is 0.05W0.17 and a wt. ratio of the Cs to the Na is 0.005W0.05. The resulting fluorescent substance coated with the filter is excellent in adhesion and gives a dense fluorescent membrane.
