CaAl₂O₄ : Eu³⁺ ��R + ( R = Li��Na��K��Rb) phosphor powder was prepared by high temperature solid-state method��in which Alumina has been extracted in wet-process as the substrate of luminescent materials used dry distillated oil shale ash��The optimal synthetic conditions are sintering temperature and time are 1 200 �� by 3 h��the concentration of fluxing agent and activated ion ratio are 3 wt% and 3 mol%��respectively�� The experiment indicated when auxiliary activated ion is Li⁺ ��the luminescent intensity of CaAl2O4 : Eu³⁺ ��Li⁺ is the strongest��The analysis of fluorescence spectrum showed that the emission spectrum exhibited a sharp peak at 615 nm�� ascribed to 5D0→7F2 transition of Eu³⁺ ��
