Abstract
Provided are phosphor particles comprising Mn-doped complex fluoride red phosphor particles and inorganic fine particles which are affixed to the surface of each red phosphor particle. The Mn-doped complex fluoride red phosphor-containing phosphor particles are suppressed in mutual adhesion and agglomeration, flow well during mixing with a silicone or epoxy resin, and have excellent humidity resistance.
