The absorbance spectra of the films were recorded using shimadzu UV – 2030 UV-Vis spectrophotometer with high sensitivity photomultiplier tube (PMT) detector, spanning wavelength range of 300 – 1100 nm. The results showed that the films exhibited high transparency with an average transmittance of approximately 80%. The optical absorption study revealed that NiO thin film has a bandgap range of 3.5 eV- 3.8 eV and a refractive index of 1.5. Notably the reflectance of the deposited films was observed to be low across the entire measured spectrum.</p> John Morka C. Okafor M. C.
