ABSTRACT Wurtzite hexagonal ZnO semiconductor nano-rods (NRs) thin films were grown on silicon substrates and silver wire with diameter equal 68 nm. Sol gel (SG) and aqueous chemical growth (ACG) methods by two steps of preparation (seed layers and nano-rod growth) are used for samples preparation. The structural and morphological properties are evaluated using X-ray diffraction (XRD) and scanning electron microscope (SEM). The proposed iron ion ...

ABSTRACT The sol-gel method is a novel technique for the preparation of thin films. In this research, gadolinium oxide (Gd 2 O 3 ) and gadolinium oxide europium doped (Gd 2 O 3 :Eu 3+ ) films prepared via the sol-gel and dip coating methods were investigated. In addition to the elaboration on the sol-gel preparation routes ...

ABSTRACT Transparent conducting films of zinc oxide and indium-doped zinc oxide have been prepared by a simple and economical sol-gel technique. This process is feasible for the fabrication of high quality TCO thin films when the processing parameters are optimized. It was found that the out-diffusion of oxygen during...
