    摘要: A luminescent material is disclosed which has the general formula:Zn.sub.1-x Cd.sub.x S:Ce.sub.y, M.sub.zwherein M is at least one alkali metal selected from Li, Na, K, Rb, and Cs, x is from about 0 to about 0.3, y and z are densities (g-atom/mol Zn.sub.1-x Cd.sub.x S) of Ce and M relative to Zn.sub.1-x Cd.sub.x S, y is from about 7.times.10.sup.-6 to about 1.5.times.10.sup.-2, and z is from about 7.times.10.sup.-6 to about 1.5.times.10.sup.-2.A method for making a luminescent material having the general formula:(ZnCd)S:Ce,Mwherein M is at least one alkali metal selected from Li, Na, K, Rb and Cs is disclosed which comprises the steps of preparing a mixture of (ZnCD)S:Ce compound, and alkali metal compound, heating the mixture under non-oxidizing atmosphere at a temperature between about 900.degree. C. and about 1170.degree. C., and quenching said mixture from said temperature.
