The Photoconductive characteristics of TiO2 films prepared by the sol-gel method, and the photovoltaic characteristics fabricated with the resulting TiO2 film and phthalocyanine nickel (NiPc) are investigated. For a TiO2 film with hydroxypropyl cellulose (Hpc) heat treated at 500°C for 10 min, the...
Pure cobalt aluminate (CoAl2O4) nanoparticles were successfully synthesized by novel sol–gel method with the aid of Co(NO3)2·3H2O, Al(NO3)3·9H2O, and gelatin without adding external surfactant or template. Besides, the effect of the dosage of gelatin on the particle size of final product...
Firstly Co–Zn ferrite nanopowder is synthesized using the sol–gel method with a composition of CoxZn(0.90-x)Al0.10Fe2O4 as presented in Fig. 1a. The x values are chosen as 0.20, 0.40 and 0.60 for Co20, Co40 and Co60 respectively. The necessary amount of Cobalt nitrate, Zinc nitrate...
