Preparation and Characterization of Pt Coated on Al-Doped ZnO Nanorods Thin Film at Different Thicknesses

Abstract:

The surfaces of Al-doped ZnO nanorods thin films were coated with platinum (Pt) by five different thicknesses; 5 nm, 10 nm, 15 nm, 20 nm and 25 nm. The resistivity decreases while the conductivity increases, proving the trend in current-voltage measurement. The transmittance spectra show diverse result. Meanwhile the 5 nm coating sample shows highest absorbance characteristic among others. This absorption coefficient was calculated from transmittance obtained by UV-vis spectra, indicating that they have high UV absorbance properties at wavelengths below 400 nm. Absorption rate might be due to the thickness of Pt that allows the penetration of UV for more oxygen absorption.
