Abstract

Abstract: Green-emitting phosphors of aluminate doped Ce³⁺,Tb³⁺,and Mn²⁺ were prepared by combustion synthesis.The phosphors of aluminate doped with Mn²⁺, Ce³⁺,and Tb³⁺ emitted character band of Mn²⁺.The luminescence and the optimum concentration of Mn²⁺ was interpreted by analysis of its structure.The luminescence of Mn²⁺ were reduced,especially the luminescence of Mn²⁺ were not observed in the phorphors while replaced Mg by Ca,Sr,and Ba.

Key words: combustion synthesis, Mn²⁺, green-emitting phosphors, luminescence
