N2 - Zinc oxide (ZnO) films with two-dimensional (2D) vertically aligned nanowalls, denoted by nanowalls-films, are successfully prepared on glass substrates at a low growth temperature of 450 °C without using metal catalysts. The morphology and optical properties of the nanowalls-film are characterized by scanning electron microscopy, X-ray diffraction analysis, transmission electron microscopy, energy dispersive X-ray spectroscopy, and photoluminescence measurement. The ZnO nanowalls-film show a strong UV emission and a preferred c-axis orientation with a hexagonal structure. The UV sensor measurement of the ZnO nanowalls-film shows a high sensitivity to UV light, rapid rise and decay times, and a good UV-to-visible rejection ratio.
