Synthesis and Characterization of ZnO and Ni Doped ZnO

Journal of Superconductivity and Novel Magnetism, 2011
ZnO and Zn1−xNixO (x=1, 2 and 3 mol %) were prepared by the sol gel via ultrasonication method with the Ni concentrations of 1, 2, and 3 mol %. The samples were characterized by high resolution scanning electron microscopy, X-ray diffraction, TEM, and UV-DRS spectroscopy.

ZnO plasmonics for telecommunications

Applied Physics Letters, 2013
Plasmonic resonances (λres's) at the telecommunication wavelengths of 1.3 and 1.55 μm can be accurately produced in ZnO layers grown at 200 °C by pulsed laser deposition in pure Ar ambient using a ZnO target with 3 wt. % Ga2O3, and then annealed in air to produce Hall-effect-determined carrier concentrations 8.8 and 6.0 × 1020 cm−3, respectively ...

The optical nonlinearities of ZnO nanoparticles and ZnO crystal

SPIE Proceedings, 2015
Based on Z-scan technique, the nonlinear absorption characteristics and nonlinear refraction characteristics of ZnO nanoparticles and ZnO crystal have been studied under the nanosecond (ns) laser pulses and the picosecond (ps) laser pulses respectively. The experimental results show that the nonlinear absorption characteristics of the ZnO nanoparticles

Thermodynamic optimization of the systems PbO-SiO2, PbO-ZnO, ZnO-SiO2 and PbO-ZnO-SiO2

Metallurgical and Materials Transactions B, 1997
Liquidus-phase equilibrium data of the present authors for the PbO-ZnO-SiO system, combined with phase equilibrium and thermodynamic data from the literature, were optimized to obtain a selfconsistent set of parameters of thermodynamic models for all phases. The modified quasichemical model was used for the liquid slag phase.

Point defects in ZnO

Faraday Discuss., 2007
We have investigated intrinsic point defects in ZnO and extended this study to Li, Cu and Al impurity centres. Atomic and electronic structures as well as defect energies have been obtained for the main oxidation states of all defects using our embedded cluster hybrid quantum mechanical/molecular mechanical approach to the treatment of localised states

Decomposition of ethanol on Cu-ZnO and Pd-ZnO

Fresenius' Zeitschrift für analytische Chemie, 1983
The decomposition of ethanol on copper and palladium covered (000¯1) ZnO faces was investigated in UHV by thermal desorption spectroscopy (TDS), Auger (AES) and by measurement of surface conductivity.

Bandgap Engineering and Doping of ZnO and ZnOS Nanocrystals

Journal of the Korean Physical Society, 2008
An active dopant modulates the property of semiconductor and thereby provides the precise control of device parameters. On the other hand if a dopant is incorporated in 2 to 5 nm size nanocrystal, the luminescent and other properties of the dopant are strongly a ected by the quantum con nement provided by the dielectric boundary of the nanocrystal.

Nanaostructured ZnO, ZnO-TiO2 And ZnO-Nb2O5 As Solid State Humidity Sensor

Advanced Materials Letters, 2012
Present paper deals with a comparative performance of n-type ZnO, ZnO-TiO2 and ZnO-Nb2O5 nanomaterials as humidity sensors. ZnO was synthesized through hydroxide route. TiO2 and then Nb2O5 were used as additives for improvement of sensitivity. Scanning electron micrograph of ZnO shows rod-like particles with average diameter 40 nm.
