The paper deals with the hydrogenated amorphous silicon (a-Si:H) films about 300 nm in thickness prepared by using rf-PECVD with hydrogen dilution R = 10 of the silane source gas in the amorphous growth regime onto clean Corning Eagle 2000 glass substrates at different deposition temperatures ranging from 50 to 200°C. Structural and optical properties of the films were obtained from X-ray diffraction...
Indium oxide (In2O3) films were directly grown on (0001)-plane sapphire substrates by atomic layer deposition (ALD) using tri-methyl-indium (TMIn) and nitrous oxide (N2O). The structural, optical and transport properties of the In2O3 films were characterized by ??-to-2?? x-ray diffractometry (XRD), field emission scanning electron microscopy (FESEM), Hall measurements, and transmission spectroscopy...
The present study focuses on the structural and optical properties of thin films of ZnO/PMMA nanocomposite deposited on glass substrate using a colloidal solution and spin-coating technique. XRD study reveals that the ZnO particles in amorphous PMMA host matrix have hexagonal (wurtzite) structure and they have arbitrary orientation. Optical absorption spectrum shows three bands in the UV-Visible area...
NdF3 single crystal was efficiently grown from the melt by the micro-pulling-down (??-PD) method. The grown crystal had a single phase confirmed by XRD. Then Optical properties and ??-ray excited scintillation properties in Vacuum Ultraviolet (VUV) wavelength region were investigated. It showed 60-80% transmittance down to 170 nm, and broad luminescence centered at 175 nm. The light yield and decay...
