摘要：
An iridium-containing group II-VI compound phosphor capable of efficiently emitting light without any economical problems or problems in energy efficiency or color purity is provided. A method for producing the phosphor is also provided. The phosphor comprises iridium and a group II-VI compound semiconductor, and the iridium is uniformly dispersed in surfaces of phosphor particles and in an inside of the phosphor particles. The method for producing the iridium-containing phosphor comprises firing an inorganic composition containing a group II-VI compound semiconductor and an iridium compound, and an iridium complex salt is used as the iridium compound.
