A fluorescent material includes at least one fluorescent compound having a structure formula of ABX.sub.ZY.sub.3-Z as defined in the specification, a plurality of NH.sub.3.sup.+ group-containing ions bound to the fluorescent compound through protonation of amine groups of an amine composition, and a plurality of COO.sup. 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.sub.H) ranges from 2.4 to 3.3 (cal/cm.sup.3).sup.1/2, and the acid composition has a total polar Hansen solubility parameter (T.sub.P) which is less than 1.4 (cal/cm.sup.3).sup.1/2.
