Figure 7 a shows the variation of band gap energy with the crystallite size, and it was observed that the energy band gap showed a decreasing trend with the increase in the crystallite size of codoped ZnO NPs, a similar trend that has also been reported by various authors. 34 , 36 − 38 It is believed that the number of atoms that form the crystallite size increases.
