论文摘要
已经在单个晶体硅和玻璃底物上通过喷雾热解技术在单个步骤中使用水和二二世溶解在二甲苯中的二层中制备了均匀分布的Fe2O3纳米颗粒的薄膜。发现纳米颗粒的尺寸分布在20 nm至30 nm的范围内。膜的特征是X射线衍射，扫描电子显微镜和拉曼光谱技术。从两个底物上的电子显微镜图像中可以明显看出生长膜的均匀性。分别使用X射线衍射和吸收光谱研究了结晶度和带隙。已经使用两种激发波长为633 nm和785 nm进行了对制备膜的拉曼测量，以研究膜的同质性深度。依赖于波长的拉曼测量结果表明，膜在两个基板上的膜厚度均匀。
Thin films of uniformly distributed Fe2O3 nanoparticles have been prepared on single crystal silicon and glass substrates by a spray pyrolysis technique in a single step using a mixture of water and ferrocene dissolved in xylene. The size distribution of nanoparticles is found to be in the range of 20 nm to 30 nm. The films have been characterized by X-ray diffraction, scanning electron microscopy and Raman spectroscopy techniques. The uniformity of the grown film was evident from the electron microscopic images on both the substrates. The crystallinity and band gap were investigated using X-ray diffraction and absorption spectroscopy respectively. Raman measurements of the prepared films have been carried out using two excitation wavelengths of 633 nm and 785 nm to investigate the depth of homogeneity of the films. The wavelength dependent Raman measurements reveal that the film is uniform across the thickness of the film on both the substrates.
