PACKAGING MATERIAL CONTAINING NON-RARE-EARTH NANOCRYSTAL PHOSPHOR, PREPARATION METHOD AND APPLICATION THEREOF

摘要

Disclosed is a packaging material containing non-rare-earth nanocrystal phosphor, a preparation method and an application thereof, which belong to the field of light emission and lighting technologies. The packaging material containing non-rare-earth nanocrystal phosphor is formed of red light and green light non-rare-earth nanocrystal phosphors and a packaging material. The present invention further provides a preparation method of the packaging material containing non-rare-earth nanocrystal phosphor, which is specifically prepared by dissolving a non-rare-earth nanocrystal phosphor in an organic solvent and then performing solvent removal and bubble removal. The packaging material containing non-rare-earth nanocrystal phosphor is applicable to white light LED, specifically, SMD LED, DIP LED, high power or thin-film white light. The non-rare-earth nanocrystal phosphor is soluble in an organic solvent to obtain homogeneous phosphor gel, thereby overcoming the defect that solution processing cannot be performed on a rare earth phosphor. The obtained LED has a high color rendering index, adjustable color temperature, and high light emission brightness.
