Process for preparing inorganic electroluminescent material

A process for preparing the inorganic electroluminescent material includes such steps as mixing CuI2 and/or CuBr2 and B2O3 and/or Al2O3 with zinc sulfate, covering it by a carbon powder layer, calcining at 1050-1300 deg.C for 2-5 hr, fast cooling acid washing, water washing, mixing it with CuI2 and/...
