Highly Transparent and Luminescent Ultra-Thin Gallium Doped ZnO Film

In this study for the first time a simple and effective method was employed for preparation of highly transparent and luminescent ultra-thin gallium doped ZnO film. By applying simultaneously ultrasonic vibration and sol-gel spin-spray coating technique, the morphology of nanoparticles was controlled and superior structural and optical properties was obtained. XRD results indicated that GZO film had a hexagonal wurtzite structure with (۱۰۱) preferred orientation. EDX studies confirmed the incorporation and presence of Ga ions into ZnO lattice structure. GZO ultra-thin film showed nearly ۹۰% transparency and strong dual blue-green emissions in the visible region which could be a novel candidate for various applications
