▎ 摘  要

We report the sol-gel spin coated method applied for preparation of ZnO-P2O5-rGO films with 1.0, 1.5 and 2.0% rGO content in precursors 'suspensions. All films presented rice-like grains of ZnO with average dimensions 30-40 nm regardless the concentration of rGO. AFM and SEM morphologic studies were done. The UV/VIS/NIR transmission spectra indicate high film transparency up to 80% for film deposited on ITO and up to 90% for films deposited on clear substrate. Spectroscopic ellipsometry method allowed with success the determination of thickness and optical constants of the film deposited on ITO covered glass substrate. The use of Tauc-Lorentz dispersion oscillator for modelling the optical constants was appropriate.
