摘要
报道了Ｌａ０．６７Ｃａ０．３３ＭｎＯδ单晶薄膜的光响应．这类钙钛矿型锰氧化物响应为测辐射热模式．新型测辐射热计宽波段光吸收系数高．调整掺杂组份和氧计量比可获得合适工作温区．此外，还报道了样品的噪声特性．
The optical response in single crystal films of La 0.67 Ca 0.33 MnO δ of manganese oxides with perovskite structure was reported. The response follows the bolometric mode fairly well. This new kind of bolometers has high absorption coefficients over a broad wavelength range. By adjusting the doping composition or oxygen stoichiometry, one can tailor the desired operating temperature. The noise properties in LCMO films were also reported.
