    Abstract: An electroluminescent phosphor comprising ZnS:Mn is disclosed. Also disclosed are ZnS:Mn electroluminescent phosphors that are free of or substantially free of copper, and/or wherein the phosphor has a D50 size of less than about 5 μm. In addition, a method for preparing a ZnS:Mn phosphor is disclosed, comprising the steps of contacting at least a portion of each of a first solution comprising a Zn2+ compound, a manganese source, and a second solution comprising a S2− source agent; and then heating the mixture at a temperature and for a time sufficient to form a phosphor.
