The band gap energy was computed using Tauc's equation, and the absorbance Spectrum was studied to ascertain their optical properties. The obtained values of the absorption peak and optical band gap were used to calculate additional significant parameters ) (Sowri Babu et al., 2013). energy. The value of n can be 1/2, 2, 1/3, or 3 in (αhv) y , the value of y=1/n represents the permitted direct, permitted indirect, forbidden direct, and forbidden indirect transitions, respectively. In this study, n=1/2 (figure ) was used to obtain the value of bandgap energy and we find that bandgap energy value 4.37 eV estimated through the plot between (αhν) 2 vs. hν, where n=1/2 was taken, which indicates allowed transition of electrons .
