Abstract:
Synthesis of thin films of nanoporous silica on glass substrate is very delicate process in sol- gel synthesis technique. Homogeneity of the film prepared and its continuity affected by the conditions of the reaction. It was found that the physical and optical properties of mesoporous thin films prepared through surfactant templating as pore size, pore volume, pore size distribution, and ordering depend on the concentration of the surfactant used. Physical properties of thin film characterized by Nitrogen adsorption isotherm, HRTEM- ED, and Photoacoustic Spectroscopy (PAS).
