In the present study, we investigated a novel green route for synthesis of zinc oxide (ZnO) nanocrystals using Prunus × yedoensis Matsumura leaf extract as a reducing agent without using any surfactant or external energy. Standard characterization studies were carried out to confirm the obtained product using UV-Vis spectra, SEM-EDS, FTIR, TEM, and XRD. In addition, the synthesized ZnO nanocrystals were coated onto fabric and leather samples to study their bacteriostatic effect against odor-causing bacteria Brevibacterium linens and Staphylococcus epidermidis. Zinc oxide nanocrystal-coated fabric and leather showed good activity against both bacteria.

The nanocrystalline ZnO thin films were deposited by pulsed laser deposition on quartz and i-Si (100) substrates at different substrate temperatures (473 K-873 K) and at different mixed partial pressures (0.05, 0.01, and 0.5 mbar) of Ar + O 2 . The structural studies from XRD spectra reveals that the films deposited at 0.05 mbar and at lower substrate temperatures were c-axis oriented with predominant (002) crystallographic orientation. At 873 K along with (002) orientation, additional crystallographic orientations were also observed in case of films deposited at 0.01 and 0.5 mbar pressures. The composition of Zinc and Oxygen in ZnO films from EDAX reveals that the films deposited at lower partial pressures were have high at.% of O 2 whereas higher partial pressures and substrate temperatures had high at.% Zn. The surface microstructure of the films show that the films deposited at lower partial pressures (0.05 mbar ) and at lower substrate temperatures (473 K) were found to have nanoparticles of size 15 nm where as films deposited at 873 K have nanorods. The length of these nanorods increases with increasing Ar + O 2 partial pressure to 0.5 mbar. The optical energy gap of the film deposited at lower partial pressure and substrate temperature was 3.3 eV and decrease with the increase of substrate temperatures. The films deposited at 0.5 mbar and at 873 K emitted an intense luminescence at a wavelength of 390 nm. The mea-K. Srinivasarao ( ) · K. Pandurangarao Post graduate department of Physics, P.G.

Molybdenum (Mo)-doped zinc oxide (ZnO) thin films were deposited by radio frequency (r.f.) magnetron sputtering on quartz and Si (100) substrates at two different substrate temperatures (473 and 673 K) and at a fixed combined partial pressure 5 Pa of Argon and O 2 . The atomic percentage (at.%) of (Mo) in ZnO was increased from 1 to 2 at.%. The results of X-ray diffraction revealed that the ZnO films deposited at 5 Pa at a substrate temperature of 473 K were highly c-axis oriented with a predominant (002) crystallographic orientation. The intensity of (002) decreased with an increase in the atomic percentage of Mo. Moreover, a growth in the (100), (101), (220), and (103) orientations was observed. The energy-dispersive spectrum (EDS) of the Mo:ZnO films deposited at 5 Pa and 473 K was substoichiometric, whereas the films deposited at 673 K were nearly stoichiometric. The surface morphology of the ZnO films is porous when deposited at 473 K. The optical energy gap of the ZnO films deposited at 473 K increased from 3.11 to 3.64 eV with an increase in the atomic percentage of Mo. The electrical resistivity of the ZnO films decreased from 1.7 × 10 −4 to 6.7 × 10 −5 Ωm with an increase in the substrate temperature and atomic percentage of Mo. The thickness of the films measured by spectroscopic ellipsometry is 440 nm.
