The invention discloses a preparation method of a room-temperature high-TCR perovskite manganese oxide film, and belongs to the field of non-refrigeration high-sensitivity infrared detection. The perovskite manganese oxide thin film is prepared from the following components: 0.70% of La, 0.18% of Ca, 0.12% of Sr and MnO3, and the perovskite manganese oxide thin film is obtained through glue preparation, aging, spin coating, pyrolysis, pre-sintering and final sintering. The prepared film is high in phase purity, high in crystallinity and flat and smooth in surface, the peak TCR temperature (Tk) is the room temperature (293-303K), the TCR reaches 10.82%/K, the preparation period is short, the cost is low, and the obtained film is flat and smooth and can be used as a detection material of an uncooled high-sensitivity infrared heat radiator.
本发明公开一种室温高TCR钙钛矿锰氧化物薄膜的制备方法，属于非制冷高灵敏红外探测领域。本发明组分为La0.70Ca0.18Sr0.12MnO3，经制胶、陈化、旋涂、热解、预烧、终烧处理得到钙钛矿锰氧化物薄膜；本发明制备的薄膜相纯度高、结晶度高、表面平整光滑、峰值TCR温度(Tk)处于室温(293‑303K)、TCR达到10.82％/K，且制备周期短、成本低、所得薄膜平整光滑，其可用作非制冷高灵敏测红外热辐射器的探测材料。
