Abstract

Zinc oxide (ZnO) thin films of multilayers structure were fabricated by chemical bath deposition (CBD) method on a glass substrate. After growing, the optical, structural and morphological characterizations of the samples were studied. Moreover, the crystallite size and energy band gap were calculated by using X-ray diffractometer (XRD) and UV-visible spectrometer, respectively. XRD showed that the crystalline size of the samples decreased with increasing the layers up to four layers, while the energy band gap increased with increasing the layers. Field emission scanning electron microscope (FESEM) used to study the morphological properties of the samples. Based on the effective atomic number, electron density and light yield properties of the samples make it suitable to be used as an ionizing radiation detector. Eventually, the samples will be used as a scintillator material to detect ionizing radiation.
