제목 Growth and characterization of Ga-doped ZnO thin films deposited by sol-gel dip-coating method
초록 Ga-doped ZnO (GZO) thin films were deposited on quartz substrates using a sol-gel dip-coating method. The structural and optical properties of the resulting GZO thin films with varying Ga concentrations were investigated using scanning electron microscopy, X-ray diffraction, UV-visible spectroscopy, and photoluminescence. The GZO thin films exhibited rough surfaces with a particle-like structure. An increase in Ga concentration gave rise to slightly decreased particle sizes but did not change the surface morphology of the thin films. From all GZO thin films, the optical transmittance in the visible region was over 80%, where in the case of the undoped ZnO thin films, three emission peaks could be observed in the UV and visible region. With an increase in the Ga concentration, the intensity of the UV emission peak increased, while the intensity of the red emission peak decreased.
