Some Properties of TiO 2 Au Nanocomposite Thin Films Produced by Spincoating Method for Applicatio
The TiO2/Au nanocomposite thin films play a very important role in the plasmonic solar cell. In such as composite systems, the localized surface plasmon resonance (LSPR) of embedded metal nanoparticles determines the light absorptionenhancement of the semiconductive part (TiO2); hence, enhances the efficiency of the plasmatic solar cell. The characterizations of the TiO2
/Au nanocomposite thin films – such as light absorption, scattering and LSPR capacities -
depend on many parameters: sizes, weight ratio of metal nanoparticles, thickness of the thin film
layers and the arrangements of TiO2/Au composite in integrated-matrix system. In this work, we
outline the preparation method of the TiO2/Au nanocomposite thin films, then we investigate the effect of technological conditions – such as TiO2/Au mixture solution concentration, TiO2/Au weight ratio and number of spin-coating layers – tothe surface morphology of the nanocomposite to find out the optimum fabrication conditions. Some experimental results of thin film such as structural property (X ray diffraction, thin film morforlogy…) and optical property (absorption coefficience concerning LSPR…) will also be shown and discussed.
