Influence of Annealing on Properties of Spray Deposited ZnO Thin Films

Figure 6

The photoluminescence spectra of ZnO thin film on glass substrate (a) unannealed, (b) annealed at 300°C, (c) annealed at 400°C, and (d) annealed at 500°C. The inset shows the intensity variation of near band edge emission at different annealed temperatures.
