“…This instability caused by tin atoms encouraged the growth of network-winkles for destress the layers and reduce the energy of the system. A similar result was found by B. Bahsi et al [23] in the study of layers of Cu and Mn doped ZnO sol-gel. Furthermore, the surface micrographs clearly showed that the doping displayed an important role for changing and improving the structure of the ZnO films.…”

In this work, Undoped Zinc Oxide (ZnO) and Sn-doped Zinc Oxide (ZnO:Sn) films have been deposited by sol-gel dip coating method, where the Sn/Zn atomic ratio was 3% and 5% in the solution. The effects of Sn incorporation on morphological, structural and optical properties of ZnO films were investigated. The Scanning Electron Microscopy (SEM) showed that the morphological surface of the films was affected by Sn low doping. The X-Ray Diffraction (XRD) patterns showed that all films have polycrystalline structures, and the doping incorporation has not lead to substantial changes in the structural characteristics of ZnO films. The crystallite size was calculated using the well-known Scherrer's formula and found to be in the range of 23 -40 nm. The measurements from UV-Visible Spectrophotometer (U-Vis) indicated that the highest average optical transmittance in the visible region was related to Undoped ZnO film, then the optical band gap and Urbach energy values of thin films were calculated. The X-Ray Photoelectron Spectroscopy (XPS) has demonstrated that Sn is incorporated in ZnO lattice.

“…Furthermore, ZnO can be used in photoconductors [3], gas sensors [4] and solar cell applications [5]. The highly preferential orientation along c-axis and wide band-gap energy of films is useful characteristics in optical wave-guides, surface acoustic wave and acoustic-optic device [6].…”

“…Wang et al ., investigated the photoluminescence and Raman characteristics of the Cu‐doped ZnO nano thin films (doping quantity from 2.0% to 4.4%) prepared by Magnetron Sputtering Method (Fig ). Banu Bashi et al ., studied the effects of Mn and Al doping on the microstructures and optical properties of ZnO thin films. The grain size of the films decreases with the increase in Mn doping and increases with the increase in Al doping.…”

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.
