摘要
The present invention relates to a surface coating method of a sulphide phosphor and thereby coated sulphide phosphor. The surface coating method includes preparing sulphide phosphor powder, applying silane modifier to the sulphide phosphor to form an organic polymer film containing silicon on the surface of the sulphide phosphor. The method further includes heat-treating the sulphide phosphor powder to obtain a silicon oxide film from the organic polymer film.
