Determination of the optical properties of fabricated CuO disks using different lasers

Abstract

In this work, copper oxide (CuO) disks were prepared using a classical pressing machine, after mixing with potassium bromide. The disks were fabricated with different thicknesses (1.7, 2.59, 3.46, 4.29, 5.49, 5.92) mm. The optical properties of CuO disk were studied using different types of monochromatic light sources in the wavelength range (300-950) nm. The incident light intensities were measured in the absence of samples, which regarded as the reference ( ), then the transmitted intensity ( ) for each sample was measured by placing the monochromatic light source, the detector, and the sample on the same line. The reflected intensities ( ) also were measured by placing the monochromatic light source and the detector at angle of 450 with the samples. The absorption coefficient for each sample was calculated using Beer-Lambert law. In addition, the refractive index for each disk also was calculated. The optical properties (absorption coefficient, transmission percentage, and refractive index) of the fabricated disks, with different thicknesses, were plotted as a function of wavelengths of the light sources . The obtained results showed the possibility of using the CuO disks as an optical filters in certain wavelengths or as reflectors for other wavelengths
