The photocatalytic degradation of Evans Blue has been studied under visible light in the presence of N-doped ZnO as a photocatalyst. N-doped ZnO was prepared by the solvent free method. The photocatalytic activity of ZnO and N-doped ZnO was compared by investigating the photodegradation of Evans Blue dye under visible light. The effect of different parameters like pH, concentration of the Dye, ...

Zeonor plastics are highly versatile due to exceptional optical and mechanical properties which make them the choice material in many novel applications. For potential use in flexible transparent optoelectronic applications, we have investigated Zeonor plastics as flexible substrates for the deposition of highly transparent ZnO and AZO thin films. Films were prepared by pulsed laser deposition ...

ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals...

europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

Atomic layer deposition (ALD) has been considered as an efficient method to deposit high quality and uniform thin films of various electron transport materials for perovskite solar cells (PSCs). Here, the effect sequence in ALD process aluminum-doped zinc oxide (AZO) on performance stability PSCs is investigated. Particularly, surface AZO film terminated by diethylzinc (DEZ)/H2O (AZO-1) or trim...

Large-scale Ni-doped ZnO nanowire (NW) arrays are grown. The electrical conductivity of a single Ni-doped ZnO NW has been increased for 30 times. The photoluminescence (PL) spectrum of the doped ZnO NWs has a red shift, suggesting possible doping induced band edge bending. The doped NW arrays could be the basis for building integrated nanoscale transistors, sensors, and photodetectors.

The development of efficient chemical sensors based on semiconductor oxides is a major challenge. Low-cost equipment fabrication with high sensor response towards H2 was the aim our work. Chemical were elaborated using zinc oxide, aluminum- and tin-doped oxide. samples synthesized cost-effective spray pyrolysis technique. Sn-doped ZnO to hydrogen gas highest followed by Al-doped ZnO, sensitivit...

The electrical resistivity values for a series of pure and doped (Co, Mn, Al) ZnO epitaxial films grown by pulsed laser deposition were measured with equipment designed for determining the direct current resistivity of high resistance samples. Room-temperature resistances ranging from 7 x 10(1) to 4 x 10(8) Omega/sq were measured on vacuum-reduced cobalt-doped ZnO, (Al,Co) co-doped ZnO, pure co...

Abstract In the present study, zinc oxide (ZnO), gold (Au) and doped (Au-ZnO) nanoparticles (NPs) were successfully synthesized through thermal decomposition of [Au(L)Cl]Cl.H 2 O [Zn(L) ].H complexes, where L is 7-[2-(BenzImidazolyl) Azo]-8-Hydroxy Quinoline (BIAHQ). Several characterization techniques such as XRD, FT-IR), UV–Vis DRS, SEM, TEM, AFM) employed to investigate phase structure, crys...
