Abstract

Official abstract text for this publication.

Disclosed is a strontium cerate luminescent material having a chemical formula of Sr 2 CeO 4 :xM and comprising the luminescent material Sr 2 CeO 4 and metal nanoparticle M, and the preparation method thereof, where M is at least one of Ag, Au, Pt and Pd, and x is a molar ratio of M to the luminescent material Sr 2 CeO 4 and 0<x≦1×10 −2 . The strontium cerate luminescent material of the present invention, through doping the luminescent material with metal particles, improves luminous intensity of the luminescent material by making use of the surface plasmon resonance generated by surface of the metal particles; besides, the doped metal ion can improve electrical conductivity of the luminescent material, and guarantee that the luminescent material has higher brightness in field emission devices or LEDs. The preparation method of the present invention has the advantages of simple operation, no pollution, easy control, low requirements for equipment, and being favorable to industrialized production.
