Abstract

The invention discloses a rare earth doped alloy oxide luminescent coating and a preparation method thereof, and relates to the field of materials engineering. An oxide metallurgical layer is formed between coating elements of the luminescent coating and matrix elements in an interdiffused manner, no obvious interfacial effect exists between the coating and the matrix, and the contents of all the elements in the metallurgy layer, from the surface to the matrix, are in gradient distribution. The method for preparing the rare earth doped alloy oxide luminescent coating is divided into three phases: pre-processing phase, alloy and rare earth co-permeation phase and plasma oxidation processing phase. According to the invention, the rare earth doped alloy oxide luminescent coating, which has luminescent property and the characteristic that the contents of rare earth oxides and matrix oxides are respectively in gradient distribution on the surfaces of metals, is prepared from rare earth and metals in an oxygen environment through co-permeation, so that the coating and the matrix are combined firmly; therefore, the rare earth doped alloy oxide luminescent coating can greatly improve the production efficiency, reduce the investment and the production cost, and achieve better economic efficiency.

Description

technical field [0001] The invention belongs to the field of material engineering, and in particular relates to a luminescent coating of alloy oxide doped with rare earth elements and a preparation method of the luminescent coating. Background technique [0002] At present, the luminescent materials prepared with oxide as the matrix mainly adopt liquid co-deposition method, sol-gel method, magnetron sputtering and other methods. People have successfully realized the doping modification of transition metal yttrium in the ordered mesoporous zirconia framework by using surfactant-assisted template and post-treatment process. The patent (CN200310117750.9) discloses a method of rapidly heat-treating sol-gel on different substrates to prepare an oxide film, by preparing a sol precursor, spin coating coating, rapid heat treatment, film formation, and cyclic operation. The preparation method of this method is The advantage is that the film components are uniform and controllable, t...
