Title:
METHOD FOR PRODUCING LUMINESCENT PARTICLES, LUMINESCENT PARTICLES, AND BIOIMAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/163808
Kind Code:
A1
Abstract:
An emulsion material comprising a host material, an organic luminescent material containing no heavy metal elements, a surfactant, and water is stirred under such conditions that the host material melts, thereby forming an emulsion, and the emulsion is cooled to produce luminescent particles having a maximum diameter smaller than 100 μm. With this method, it is possible to provide luminescent particles which exhibit a high luminescent efficiency in water and are highly safe.
