Luminescence of Ce3+ ion in aluminate based phosphors for scintillator

Ce³⁺ activated aluminate based phosphors prepared by combustion synthesis are reported here. The emission of Ce³⁺ ion is observed around 321–354 nm in the ultraviolet region of the spectrum. The intensity of strong photoluminescence emission peak of Ce³⁺ ion increases when Mg is added to CaAl₁₂O₁₉ phosphor. The Ce³⁺ emission in CaAl₁₂O₁₉:Ce,Mg phosphor may be useful for scintillation application.
