Controlling the growth of particle size and size distribution of silica nanoparticles by the thin film structure Authors:
Publisher and Date:(Springer, 2012)Nanostructured silicondioxide thin films were prepared by sol-gel spin coating technique. The SiO2 films were made using a conventional mixture of tetraethoxysilane (TEOS) deionized water and ethanol with various NH3/TEOS ratios. The nanostructured silica films were made using a mixture of the SiO2 sol and regular SiO2 sol to control the enlargement of the particles inside the films. The structural morphological and optical characterizations of the as-deposited and annealed films were carried out ...
Publisher and Date:(Elsevier Science, 2014)In this work the ZnO were fabricated with the sol-gel spin coating method and the effects of the Dea:water ratios on the properties of the as-prepared ZnO thin films were determined by using a X-ray diffractometer transmission electron microscope scanning electron microscope atomic force microscope ultraviolet-visible spectrophotometer and spectrophotometer. Experimental results indicated that the Dea:water ratio affected the structural and optical properties of the ZnO films considerably. The ...
