Al–Sn co-doped ZnO thin films were fabricated onto quartz glass substrates by the sol-gel method. The surface morphology, electrical and optical properties at different post-deposition heating temperatures were investigated. The grains of preferred c-axis showed a well-mixed microstructure and the peak height was enhanced with the post-deposition heating temperature increasing from 400°C to 600°C. Doped films showed a preferential orientation along the (002) plane, while the preferential orientation changed to the (101) plane when temperature was higher than 500°C. The lowest resistivity 6×10–3Ω•cm was observed from samples made at 500°C, with an average 91.2% optical transmittance in the visible range. In this study, optical band gap of all the doped films were broadened, regardless of post–deposition heating temperature.

Undoped, Al-doped and Al-B co-doped ZnO transparent semiconductor thin films were deposited on glass substrates by sol-gel method and spin coating technique. This study investigated the influence of Al (2 at.%) doping and Al (2 at.%)-B (1 or 2 at.%) co-doping on the microstructural, surface morphological, electrical and optical properties of the ZnO-based thin films. XRD analysis indicated that all as-prepared ZnO-based thin films were polycrystalline with a single-phase hexagonal wurtzite structure. The substitution of extrinsic dopants (Al or Al-B) into ZnO thin films can significantly degrade the crystallinity, refine the microstructures, improve surface flatness, enhance the optical transparency in the visible spectrum and lead to a shift in the absorption edge toward the short-wavelength direction. Experimental results showed that the Al-doped and Al-B co-doped ZnO thin films exhibited high average transmittance (>91.3%) and low average reflectance (<10%) in the visible region compared with the ZnO thin film. The optical parameters, including the optical bandgap, Urbach energy, extinction coefficient and refractive index, changed with the extrinsic doping level. Measured results of electrical properties revealed that the singly doped and co-doped samples exhibited higher electron concentrations and lower resistivities than those of the undoped sample and suggested that 2 at.% Al and 1 at.% B were the optimum dopant concentrations for achieving the best electrical properties in this study.
