Abstract: An organic light-emitting device containing a compound having a lone electron pair and a π electron orbital, the compound emitting fluorescent light by such a mechanism that when at least a part of electrons constituting the lone electron pair is excited to an excited triplet state 3nπ* through nπ* transition, the part of electrons undergoes inverse intersystem crossing from the excited triplet state 3nπ* to an excited singlet state 1nπ*, and returns from the excited singlet state 1nπ* to the ground state, at which the fluorescent light is emitted. The organic light-emitting device has a high light emission efficiency.

Abstract: Luminescent particles with a maximum diameter of less than 100 μm are produced by stirring an emulsion material, including a host material, an organic luminescent material containing no heavy metal element, a surfactant and water, under conditions that melt the host material, thereby forming an emulsion, and then cooling the emulsion. This method can provide luminescent particles which are highly safe and which exhibit high luminous efficiency in water.
