Aluminum-doped zinc oxide (AZO) nanorod array thin film with hydrogen treatment possesses the functions of transparent conducting oxide thin film and 1-D nanostructured semiconductor simultaneously. To enhance the absorption in the visible light region, it is sensitized by cadmium sulfide (CdS) nanoparticles which efficiently increase the absorption around 460 nm. The CdS nanoparticles-sensitiz...

Model-type thin films of Gd doped and Gd/Mn co-doped ceria were investigated by means of impedance spectroscopy in a humid H2 atmosphere. A novel measurement technique for microelectrodes with interdigitating Pt current collectors was employed. This method allows a separation of the different elementary processes contributing to the electrode impedance. After annealing at 650°C in humid H2 atmo...

A series of nitrogen-doped porous graphene foams (NPGFs) have been prepared by hydrothermally treating a mixed solution of graphite oxide (GO) and ammonia. The NPGFs are used as the counter electrode (CE) material for dye-sensitized solar cells (DSCs) in conjunction with the conventional iodide-based electrolyte and the recently developed sulfide-based electrolyte. Tafel-polarization tests and ...

in this study, undoped zno and doped with fe and mn nanostructures were synthesized by hydrothermal method. the morphology of nanostructures was characterized by scanning electron microscope. the electrochemical response of the carbon paste electrode modified with nanoparticles of zno and also zno doped with fe and mn toward levodopa (l-dopa) was studied. studies of cyclic voltammetry using pro...

L-alanine cadmium chloride (LACC) crystals doped with thiourea were grown by slow evaporation technique. The solubility of the samples were determined gravimetrically at various temperatures in the range 30 50 o C. Single crystals of thiourea doped L-alanine cadmium chloride were tested for the crystal structure by single crystal XRD studies. The values of SHG efficiency and laser damage thresh...

the physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of b3lyp/6-31g* at the level of theory on gaussian 03 software. a variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

Photoluminescence (PL) of zinc sulfide powder synthesized and doped with Mn 2+ Eu 3+ ions by the method emerging reagents in a dodecane medium was investigated. In absorption excitation spectra PL samples ZnS : (Eu ), bands corresponding to transitions electrons from valence band conduction levels structural defects ZnS, as well transition 4f-electrons ground 7 F 0 excited electronic states wer...

The recent advances in the photorefraction of doped lithium niobate crystals are reviewed. Materials have always been the main obstacle for commercial applications of photorefractive holographic storage. Though iron-doped LiNbO3 is the mainstay of holographic data storage efforts, several shortcomings, especially the low response speed, impede it from becoming a commercial recording medium. Thi...
