【 摘 要 】

Composite materials of zinc oxide (ZnO) and graphene oxide (GO) have caused emergence of potential application in the field of optoelectronics. Phosphate based glasses (P2O5) can improve the conductivity and increase the graphene oxide (GO) concentration and homogeneity distribution in the films. This paper presents a comparative study of two types of composite thin films: ZnO/P2O5/GO and ZnO/GO deposited through a sol-gel process on glass substrates. Optical analysis derived from spectroscopic ellipsometry was involved calculating the reflectance spectral curves for different thicknesses of the thin film layers constituting the ZnO/P2O5/GO and ZnO/GO.
