Abstract
A composite thin film includes N thin film layers stacked one over another in sequence from a first thin film layer to an N-th thin film layer. N is an integer satisfying 3≤N≤9. The N thin film layers are nano-ZnO thin films. A nano-ZnO particle size of the nano-ZnO thin films gradually increases or decreases from the first thin film layer to the N-th thin film layer.
