  • Fluorescent material and method for making the same
    Patent number: 11059726
    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 (T?H) ranges from 2.4 to 3.3 (cal/cm3)1/2, and the acid composition has a total polar Hansen solubility parameter (T?P) which is less than 1.4 (cal/cm3)1/2.
