Title:
蛍光材料及びその製造方法
Document Type and Number:
Japanese Patent JP6860597
Kind Code:
B2
Abstract:
A fluorescent material includes at least one fluorescent compound having a structure formula of ABXZY3-Z as defined in the specification, a plurality of NH3+ group-containing ions bound to the fluorescent compound through protonation of amine groups of an amine composition, and a plurality of COO− group-containing ions bound to the fluorescent compound through deprotonation of carboxyl groups of an acid composition. The amine composition has a total hydrogen bonding Hansen solubility parameter (TδH) ranges from 2.4 to 3.3 (cal/cm3)1/2, and the acid composition has a total polar Hansen solubility parameter (TδP) which is less than 1.4 (cal/cm3)1/2.
