Phosphorescent light emitting material, method for emitting phosphorescence from phosphorescent light emitter, method for producing phosphorescent light emitting material, organic light emitting device and gas sensor

摘要

To provide a phosphorescent material that emits phosphorescence at a high emission intensity at room temperature, using a phosphorescent material that does not emit phosphorescence at 25 ° C. The phosphorescent light emitting material of the present invention is a phosphorescent light emitting material in which a hollow body having a hollow region encloses a phosphorescent emitter, and phosphorescent radiation from the phosphorescent emitter at 25 ° C. is contained in the hollow body. This is not observed in a state where the phosphorescent light emitter is not formed, but is observed in a state where the phosphorescent light emitter is encapsulated in the hollow body.
