Fluorite type high-entropy oxide powder with ultraviolet visible light response and preparation method of fluorite type high-entropy oxide powder
The invention belongs to the field of high-entropy oxide materials, and particularly discloses fluorite type high-entropy oxide powder with ultraviolet visible light response and a preparation method of the fluorite type high-entropy oxide powder. The non-equimolar-ratio high-entropy oxide powder with a fluorite type structure is prepared by adopting a method of dissolving, precipitating, drying and sintering in sequence, and the chemical formula of the high-entropy oxide powder is (Ce1/2Zr1/2) 1-x (La1/3Y1/3RE1/3) xO2-delta. The preparation process of the oxide powder is simple, the powder is uniformly dispersed and has a spectral response band in a near ultraviolet region, and the prepared oxide powder has relatively high sensitivity to light with the wavelength of 200-400nm.
本发明属于高熵氧化物材料领域，具体公开了一种具有紫外可见光响应的萤石型高熵氧化物粉体及其制备方法。依次采用溶解、沉淀、干燥和烧结的方法制备了具有萤石型结构的非等摩尔比的高熵氧化物粉体，其化学式为(Ce1/2Zr1/2)1‑x(La1/3Y1/3RE1/3)xO2‑δ。该氧化物粉体的制备工艺简单，粉体分散均匀，具有近紫外区的光谱响应谱带，所制备的氧化物粉体对波长在200‑400nm之间的光具有较高的灵敏度。
