Lanthanum manganate ceramic-based light absorber and application and preparation method thereof
The invention belongs to the technical field of photoelectricity, and particularly relates to a lanthanum manganate ceramic-based light absorber, application of the light absorber and a preparation method of the lanthanum manganate ceramic-based light absorber. The light absorber comprises a ceramic substrate, an anti-laser-damage film and a nanometer transition layer. The ceramic substrate comprises five structural layers; comprising a lithium-doped lanthanum manganate ceramic layer located in a middle layer; the calcium-doped lanthanum manganate ceramic layers are positioned on two sides of the lithium-doped lanthanum manganate ceramic layer; the compact lanthanum manganate ceramic layers are positioned on two sides of the calcium-doped lanthanum manganate ceramic layer. The sizes of pores in the ceramic matrix are distributed in a gradient decreasing mode from the middle to the two sides. And the laser-damage-resistant film is positioned on the outer surface of the lanthanum manganate ceramic layer. And the nano transition layer is generated at the interface of the ceramic substrate and the laser-damage-resistant thin film after high-temperature heat treatment of adjacent structural layers in the ceramic substrate and the laser-damage-resistant thin film. The problem that an existing light absorber cannot achieve balance in absorption spectrum, absorptivity, heat resistance, shock resistance, laser damage resistance and the like is solved.
本发明属于光电技术领域，具体涉及一种锰酸镧陶瓷基光吸收体，该光吸收体的应用，以及锰酸镧陶瓷基光吸收体的制备方法。该光吸收体包括陶瓷基体、抗激光损伤薄膜和纳米过渡层。陶瓷基体包括五个结构层；包括位于中间层的锂掺杂锰酸镧陶瓷层；位于锂掺杂锰酸镧陶瓷层两侧的钙掺杂锰酸镧陶瓷层；以及位于钙掺杂锰酸镧陶瓷层两侧的致密的锰酸镧陶瓷层。陶瓷基体中的孔隙尺寸从中间向两侧呈梯度递减的分布状态。抗激光损伤薄膜位于锰酸镧陶瓷层的外表面。纳米过渡层由陶瓷基体和抗激光损伤薄膜中的相邻结构层经高温热处理后生成在二者的界面处。本发明克服了现有光吸收体无法在吸收光谱、吸收率、耐热抗震和耐激光损伤等性能上达到均衡的问题。
