Reflectance and spectrophotometric analysis of copper oxide (Cu2O) surface layer

Abstract

This paper presents a study conducted to determine the relationship between the thickness of copper oxide and its dominant reflectance color. Reflectance spectra from the copper oxide are used to determine the dominant color with the aid of a chromaticity diagram. Results showed an increase in thickness up to 91.89 μm improves the reflectance and the green range.
