Abstract
A rare earth ion doped lanthanum gallate luminous material containing metal particles and preparation method thereof are provided. The chemical formula of the lanthanum gallate luminous material is LaGaO:Ln,M, wherein Ln is one or more of Tm, Tb, Euand Sm, M is one of Ag, Au, Pt and Pd, the value range of x is 0.001 to 0.1, and the value range of y is 0.00002 to 0.01. The luminous performance of the lanthanum gallate luminous material can be greatly improved under the same excitation condition and the wavelength of emission light doesn't change, due to the introduction of metal particles into the rare earth ion doped lanthanum gallate luminous material. The lanthanum gallate luminous material has excellent luminous performance, and its emitting photochromic purity and light emitting luminance after excitation are high, so it can be used widely in various kinds of light emitting devices.
