Thermal photovoltaic rare earth high-entropy aluminate ceramic selective emitter and preparation method and application thereof
The invention discloses a rare earth high-entropy aluminate ceramic emitter for thermophotovoltaic and a preparation method and application of the rare earth high-entropy aluminate ceramic emitter. The chemical formula of a material of the rare earth high-entropy aluminate ceramic emitter for thermophotovoltaic is (Y < 0.2 > R < 0.2 > Ho0 < 0.2 > Er < 0.2 > Yb < 0.2 >) < 3 > Al < 5 > O < 12 >, wherein R is selected from Dy or Gd. According to the rare earth high-entropy aluminate ceramic prepared by the preparation method disclosed by the invention, metal ions participating in the structure comprise five rare earth ions, and the rare earth ions have a relatively unique selective absorption characteristic, so that the rare earth high-entropy aluminate ceramic shows a relatively good application prospect in the field of thermophotovoltaic nuclear batteries.
本发明公开了一种热光伏用稀土高熵铝酸盐陶瓷发射体及其制备方法和应用，该热光伏用稀土高熵铝酸盐陶瓷选择性发射体的材料的化学式为：(Y0.2R0.2Ho0.2Er0.2Yb0.2)3Al5O12；其中，R选自Dy或Gd。本发明制备的稀土高熵铝酸盐陶瓷，由于参与结构的金属离子有五种稀土离子，由于稀土离子具有较为独特的选择性吸收特性，这使其在热光伏核电池领域展现出较好的应用前景。
