摘要

采用溶胶-凝胶法制备了未掺杂和掺杂Sr2+的纳米晶YFeO3。用x射线衍射和x射线微量分析测定了其结构和元素组成。合成的纳米粉体通过自旋镀膜在硅衬底表面制备了薄膜。在空气和待测气体存在的情况下，表面电阻率测量表明，这样制备的材料对NH3和CO有传感器响应。气体浓度为50 ppm，传感器信号超过50%。

Preparation of Gas-Sensing Thin Sr2+-Doped YFeO3 Films

Nanocrystalline undoped and Sr²⁺-doped YFeO₃ has been prepared by sol–gel synthesis. Its structure and elemental composition have been determined by X-ray diffraction and X-ray microanalysis. Thin films of the synthesized nanopowders have been produced on the surface of silicon substrates by spin coating. Surface resistivity measurements in air and in the presence of the gases to be detected have demonstrates that the materials thus prepared have a sensor response to NH₃ and CO. The concentration of the gases was 50 ppm, and the sensor signal exceeded 50%.

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
