Fours pour le sulfurisation et selenisation de cellules ...

+

As a source for selenium and sulfur, the gases hydrogen selenide H 2 Se and hydrogen sulfide H 2 S are used. On this CIGSlayer, also named absorber layer, a thin film of Cadmiumsulfid CdS is deposited, followed by another layer of a transparent conductive oxide TCO, serving as a front side contact and consisting of Zincoxide ZnO. At the interface between the CdS and the CIGSlayer the ...

Microwave synthesized ZnO nanorod arrays for UV sensors: A ...

+

The present work reports the influence of zinc oxide (ZnO) seed layer annealing temperature on structural, optical and electrical properties of ZnO nanorod arrays, synthesized by hydrothermal method assisted by microwave radiation, to be used as UV sensors. The ZnO seed layer was produced using the spincoating method and several annealing temperatures, ranging from 100 to 500 °C, have been ...

Zinc Oxide Nanorods as H2S Gas Sensor Semantic Scholar

+

The zinc oxide nanorods have been synthesized and studied as the sensing element for the detection of H2S gas. The zinc oxide nanorods were synthesized by precipitation method. The thick films of synthesized material were prepared by screen printing method on glass substrate. Gas sensing properties of zinc oxide thick films were studied forH2S, LPG and NH3 gases by changing the …

H2S gas sensing properties of bare and Pdfunctionalized ...

+

The multiple networked CuO nanorod sensors showed a response of 400% at 100 ppm H2S at 300 °C, whereas the Pdfunctionalized CuO nanorod sensors showed a response of 31,243% under the same ...

CuO nanoparticle decorated ZnO nanorod sensor for low ...

+

The high sensitivity, reversible response and good selectivity of the synthesized heterostructured porous CuO/ZnO nanorod hybrid indicated its potential application as a chemical sensor. CuO nanoparticle decorated porous ZnO nanorods were synthesized via a twostage solution process. First, porous ZnO nanorods were fabricated by a lowtemperature hydrothermal method.

Scattering of light by ZnO nanorod arrays — Pontificia ...

+

Resultado de la investigación: Contribución a una revista › Artículo › revisión exhaustiva. Información general; Huella; Resumen. The optical properties of ZnO nanorod (NR) arrays were investigated by optical total transmittance (TT) and diffuse reflectance (DR) spectroscopy in the visible region. The NRs were grown electrochemically in a threeelectrode cell over a glass/fluorine ...

Mechanism Study of ZnO NanorodBundle Sensors for H2S Gas ...

+

The response of ZnO nanorodbundle sensors to H2S gas increased with Ts; this trend may be due to chemical reaction of nanorods with gas molecules. Xray photoelectron spectroscopy results indicated that the sensing mechanism of the ZnO nanorodbundle sensor was explained by both the wellknown surface reaction between H2S and adsorbed oxygen on ZnO, and the formation of zinc sulfur bonding …

Room temperature CO2 sensing using Audecorated ZnO ...

+

Zinc oxide nanorods decorated with gold nanoparticles were deposited on an optical fiber and were used for carbon dioxide gas detection at room temperature. This optical gas sensor is based on the changes in the intensity of transmitted light due to the interaction of gas molecules with zinc oxide surface. Zinc oxide nanorods were prepared by ultrasonic method and were decorated with ...
