The aim of this article is to provide a systematic method to perform numerical and experimental evaluation on the optical properties of Al ‐doped ZnO nano thin films. Some different doping density samples are deposited for testing the transmittance. The results show that the transmittance of Al ‐doped ZnO has a nonlinear relation with the optical constants and Al ‐doped quantity. The optical band gap of the Al ‐doped ZnO decreases with the Al doping quantity increasing. Meanwhile, the Maxwell‐Garnett ( MG ) theory is used to investigate the optical properties of Al ‐doped ZnO nano thin films in visible range. The comparison can illustrate the validity of both test and design method. It implies a potential design and evaluation method for developing a new type of ceramic nano thin film in engineering.
