Fluorescent materials and preparation methods thereof are provided. The fluorescent materials are represented by the general formula: M, ZnAlO and YO: Re, wherein Re is at least one selected from Eu and Tb, M is at least one selected from Ag, Au, Pt and Pd in the form of nano-particle, and 0&#x3c;&#xd7;&#x2266;0.05. The said methods include the following steps: step, preparing a colloid of ZnAlO; step, preparing a colloid of Y and Re containing the metal element M; step, mixing the colloid of ZnAlO with the colloid of Y and Re, aging and heating treatment to form the fluorescent materials. Compared to the YOfluorescent materials in the art the present fluorescent materials have higher luminescence efficiency, conductivity, long life and industrial applicability.

Yttrium oxide phosphor mixture and preparation method thereof

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.
