摘要

本研究采用化学沉淀法对MgO:SnO2纳米颗粒的结构和光学性质进行了研究,并采用自旋镀膜技术在玻璃衬底上沉积了薄膜。x射线衍射分析证实了所制备薄膜的晶体结构,其峰对应于(110)、(101)、(200)、(211)和(220)面,并利用SnO2的四方晶体结构,利用傅里叶变换红外(FTIR)和扫描电子显微镜(SEM)表征了所合成的金属氧化物纳米颗粒的官能团、形状和尺寸。利用紫外可见光谱对薄膜的光学性质进行了研究,估计其带隙能量在(3.9 ~ 3.4 eV)之间。测定了薄膜的折射率和消光系数,结果表明薄膜在可见光区具有良好的透明度。研究表明,采用自旋镀膜技术制备的MgO:SnO2薄膜在光电子学和气体传感器方面具有潜在的应用前景。

Enhancements of Structural and Optical Properties of MgO: SnO2 Nanostructure Films
This study investigates the structural and optical properties of MgO:SnO2 nanoparticles using the Chemical precipitation method, The thin films were deposited by the spin coating technique on glass substrates. X-ray diffraction analysis proved the crystalline structure of prepared thin films, with the peaks corresponding to the (110), (101), (200), (211), and (220) planes, with the tetragonal SnO2 crystal structure, Fourier transforms infrared (FTIR), and scanning electron microscope (SEM) used to characterize the functional groups, shape, and dimensions of synthesized metal oxide nanoparticles. The optical properties of the films were studied by UV-Vis spectroscopy, and the bandgap energy was estimated to be in the range of (3.9 - 3.4 eV). The refractive index and extinction coefficient of the films were also determined, and the results indicated that the films had good transparency in the visible region, The study concludes that MgO:SnO2 thin films obtained by spin coating technique have potential applications in optoelectronics and gas sensors.
