Details of preparation of two component calcium halophosphate daylight phosphor 6500' K doped wilh antimony and manganese by high temperature solid state reaction between CaHPO,, CaCO,, CaF,. SrCI,, Sb203 and MnC0, are reported. The effects of varying the activator concentration, metal to phosphorus ratio and chlorine to fluorine ratio on the photoluminescence of the light blue and warmwhite phosphors are discussed. Optimum values of the above parameters in the preparation of the two components, the blending of which leads to a daylight phosphor 6500'K are given.
