New phosphors are required for the advancement of lighting and display technologies. One of the most effective ways for new phosphors is to employ new materials for host materials. It takes much time and labor to develop new materials from powder synthesis or single crystal growth. However, even if the powder product is a mixture phase, each particle is a single phase and a single crystal. The single particle diagnosis approach focuses on the tiny single crystal particle. Here we show the concept of the single particle diagnosis approach and some examples of new phosphor discovery by this approach.
