The present invention is related to a phosphor that can be excited by UV light between 375 to 400 nm to emit white light, which is intrinsically produced by emitting blue light with yellow light simultaneously. This compound is synthesized from organic amine, metal oxide and phosphate under hydrothermal conditions, and gives rise to a zeolitic structure with the chemical formula of (A).sub.5-x/2[Zn.sub.9-xGa.sub.xO(HPO.sub.4)(PO.sub.4).sub.8].yH.sub.2O (0
