Optical characterization of oxide encapsulated silicon nanowires of various morphologies.

Morphological, structural and photoresponse characterization of ZnO nanostructure films deposited on plasma etched silicon substrates

ZnO nanostructure films were deposited by radio frequency (RF) magnetron sputtering on etched silicon (100) substrates using dry Ar/SF6 plasma, at two etching times of 5 min and 30 min, and on non etched silicon surface. Energy dispersive X-ray (EDX) technique was employed to investigate the elements contents for etched substrates as well as ZnO films, where it is found to be stoichiometric. Su...

Synthesis, characterization and investigation of optical and photocatalytic properties of zinc oxide nanoparticles in three different rod, spherical and sheet morphologies

In the present study, zinc oxide nanoparticles in three different forms (spherical, rod and sheet) were synthesized by a hydrothermal method. The obtained products were characterized by X-ray diffraction (XRD), filed emission scanning electron microscopy (FESEM), EDX elemental analysis and UV-Vis spectroscopy. The photocatalytic properties were investigated using congo red (CR) degradation unde...

Synthesis and Characterization of Nanowires Zinc Oxide with Different Temperatures

Area Effect of Reflectance in Silicon ‎Nanowires Grown by Electroless Etching

This paper shows that the reflectance in silicon nanowires (SiNWs) can be optimized as a function of the area of silicon substrate where the nanostructure growth. SiNWs were fabricated over four different areas of silicon substrates to study the size effects using electroless etching technique. Three different etching solution concentrations of silver nitrate (AgNO3) and hydroflu...

Synthesis, Characterization and Application of Zinc Oxide with Micro Polyhedral and Nano Plate Morphologies for Simultaneous Decolorization of Two- dye Mixture in Wastewater

In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...
