摘      要：The nanostructured titanium dioxide(TiO_(2))thin films have been prepared for the molar concentrations of titanium tetra isopropoxide(TTIP)0.05 M,0.1 M,0.15 M and 0.2 M by sol-gel routed spin coating technique with calcination at 450℃.The processing parameters such as,pH value(8),catalyst HCl(0.1 ml),spin speed(3000 rpm)and calcination temperature(450℃)are *** crystalline nature and surface morphology were analyzed by XRD,SEM and AFM *** XRD results confirm that the films are crystalline with anatase phase,and are *** SEM micrographs of the TiO_(2) film reveal the spherical nature of the *** analysis establishes that the uniformity of the TiO_(2) thin film was optimized at 0.2 *** optical measurements show that the transmittance depends on the molarity,and the optical band gap energy of TiO_(2) films is found to be inversely proportional to *** I-V characteristics exhibit that the molarity strongly influences the electrical conductivity of the *** results indicate that the significant effect of molarity on structural,optical and electrical properties of the nanostructured TiO_(2) thin films will be useful to photovoltaic application.
