Abstract

See full text

The present invention relates to a lutecium oxide luminescent material, having the general molarcular formula of Lu2-xO3:Lnx3+@SiO2@My, wherein Ln is selected from one of the elements Eu, Tb, Dy, Sm, Er, Ho and Tm; M is selected from at least one of Ag, Au, Pt, Pd and Cu metallic nanoparticles; 02-xO3:Lnx3+, 0−2; @ represents coating; the lutecium oxide luminescent material uses M as a core, SiO2 as an inner shell, and Lu2-xO3:Lnx3+ as an outer shell. The lutecium oxide luminescent material is formed into a core-shell structure through the coating of at least one of Ag, Au, Pt, Pd and Cu metallic nanoparticles. The metallic nanoparticles can improve the internal quantum efficiency of the luminescent material, thus enabling the lutecium oxide luminescent material to have a relatively high luminous intensity.
