We report, for the first time, the synthesis of the high-quality p-type ZnO NWs using a simple chemical vapor deposition method, where phosphorus pentoxide has been used as the dopant source. Single-crystal phosphorus doped ZnO NWs have their growth axis along the 001 direction and form perfect vertical arrays on a-sapphire. P-type doping was confirmed by photoluminescence measurements at vario...

Cu-doped p-type ZnO films are grown on c-sapphire substrates by plasma-assisted molecular beam epitaxy. Photoluminescence (PL) experiments reveal a shallow acceptor state at 0.15 eV above the valence band edge. Hall effect results indicate that a growth condition window is found for the formation of p-type ZnO thin films, and the best conductivity is achieved with a high hole concentration of 1...

PURPOSE To evaluate changes in the physicochemical properties, water sorption (WS), solubility (SO), modulus of elasticity (E), ultimate tensile strength (UTS), and microhardness (MH) tests were undertaken in zinc-doped dental adhesives. METHODS Two bonding resins, Adper Single Bond Plus (SB) and Clearfil SE Bond (SEB), were zinc-doped by mixing them with 5, 10 or 20 wt% of ZnO powder, or wit...

The aqueous-based Zn-ammine complex solutions represent one of the most promising routes to obtain the ZnO electron transport layer (ETL) at a low temperature in inverted organic solar cells (OSCs). However, to dope the ZnO film processed from the Zn-ammine complex solutions is difficult since the introduction of metal ions into the Zn-ammine complex is a nontrivial process as ammonium hydroxid...

Zinc oxide and Ga-doped ZnO nanowires and nanorods are synthesized on various substrate like Fluorine doped tin oxide glass plate, SiO2 coated Silicon substrate and aluminum nitride coated silicon substrates. The coating process carried out using zinc oxide sol-gel solution. The synthesized material was characterized using XRD (X-ray diffraction), FE-SEM (Field emission scanning electron micros...

undoped and mn-doped zno nanoparticles were successfully prepared by the hydrothermal method with different annealing temperature conditions. structural, chemical and optical properties of the samples were studied by x-ray diffraction (xrd), field emission scanning electron microscopy (fesem), uv-vis spectrophotometry and fourier transform infrared (ft-ir) spectroscopy. the phase purity was con...

This paper reports the photoluminescence studies of Eu (RE)-doped ZnO nanophosphors synthesized by precipitation method using ethanolic solution as solvent. The prepared samples are characterized by a Philips Holland TW 1710 XRD measuring instrument with Co target. The ZnO structure is found to be wurtzite. The particle sizes are found to be in the range of 70 nm to 90 nm. The prominent peaks f...

In this study, the performance and stability of inverted bulk heterojunction (BHJ) polymer solar cells (PSCs) is enhanced by doping zinc oxide (ZnO) with 0-6 wt % cetyltrimethylammonium bromide (CTAB) in the sol-gel ZnO precursor solution. The power conversion efficiency (PCE) of the optimized 3 wt % CTAB-doped ZnO PSCs was increased by 9.07%, compared to a PCE of 7.31% for the pristine ZnO dev...

Undoped Zinc oxide (ZnO) nanoparticles as well as ZnO nanoparticles doped with Magnesium (Mg) were synthesized by wet chemical precipitation method using Zinc acetate and Magnesium acetate in Ethylene glycol and distilled water medium. The prepared nanoparticles were characterized with X-ray diffraction (XRD). The XRD patterns show the pattern of typical ZnO nanoparticles and correspond with st...

Zinc oxide is a very interesting material for several technological applications. The properties of ZnO materials have been investigated and the influence of the 3D structure has been evaluated. Controlling experimental parameters is possible to obtain branched structures, which results in the preparation of materials presenting high surface area. Herein, we present a hydrothermal procedure to ...
