COATED PHOSPHOR AND METHOD FOR PRODUCING COATED PHOSPHOR

The object of the present invention is to provide a coated phosphor in which the release of sulfur-based gas in high-temperature, high-humidity conditions can be suppressed. A coated phosphor (1) has a structure in which a sulfide phosphor (2) is coated with a silicon dioxide film (4) containing a m...
