| 简介 |
Provided is a sulfur oxide luminescent material. The luminescent material has a general chemical formula of Ln 2-x O 2 S : Eu x 3+ @M y , wherein@ is coating, Eu is doped in Ln 2-x O 2 S, Ln 2-x O 2 S : Eu x 3+ has a porous structure, and M is located in pores of the Ln 2-x O 2 S : Eu x 3+ . In the sulfur oxide luminescent material, metal nano particles coating is used to form a core-shell structure, which increases luminescent efficiency of the sulfur oxide luminescent material in a same excitation condition; in addition, a hollow structure is formed between a core and a shell layer of the sulfur oxide luminescent material, which effectively reduces usage of rare earth elements in the shell layer and lowers cost of the luminescent material. Also provided is a preparation method for the sulfur oxide luminescent material. |
