Enhanced H2 sensing performance presented by Mg doped ZnO films fabricated with a novel ITO seed layer
Journal of Materials Science: Materials in Electronics - Tập 26 - Trang 3458-3465 - 2015
K. Vijayalakshmi, A. Renitta
The present study investigates the influence of Mg doping on the H2 sensing properties of ZnO films fabricated with ITO seed layer by spray pyrolysis method. XRD results revealed that both undoped and Mg doped ZnO films were polycrystalline with a hexagonal wurtzite structure with highly oriented (002) plane perpendicular to the ITO substrate. The films were highly transparent in the visible range...... hiện toàn bộ

Investigation of morphology, a.c. electrical and optical properties of nanostructured thin film of polypyrrole–bromoaluminium phthalocyanine
Journal of Materials Science: Materials in Electronics - Tập 24 - Trang 764-769 - 2012
Mohammad E. Azim-Araghi, Sobhenaz Riyazi
In this research, nanocomposite polypyrrole (PPy) + 30 % bromoaluminium phthalocyanine (BrAlPc) was prepared in our laboratory. Optical absorption and field emission scanning electron microscopy characterized the thin films. The powder of nanocomposite was characterized by X-ray diffraction. The nanocomposite PPy + 30 % BrAlPc thin film deposited on pre-cleaned glass substrate with a thickness of ...... hiện toàn bộ
Influence of In-doping on microstructure, optical and electrical properties of sol–gel derived CdO thin films
Journal of Materials Science: Materials in Electronics - Tập 29 - Trang 11286-11295 - 2018

Cadmium oxide thin films have been prepared on glass substrates by the sol–gel (SG) spin-coating technique. The structural, optical and electrical properties of the prepared films were studied as a function of the thicknesses. The results show that the optimum thickness for preparation of CdO films with high optical transparency and low resistivity is 211 nm. By using this optimized thicknesses an...... hiện toàn bộ
Synthesis and photoluminescence studies of Na3−3xLnxSbO (PO4)2 (Ln = Eu, Sm and Tb, and 0 ≤ x ≤ 0.1 mol%) phosphors for white light-emitting diodes

In this work, we report the conventional solid-state synthesis, characterization and emission spectral properties of Na3−3xLnxSbO(PO4)2 (Ln = Eu, Sm and Tb, 0 ≤ x ≤ 0.1 mol%) phosphors. The powder X-ray diffraction (XRD) pattern of prepared phosphors consists of single-phase orthorhombic structure with space group P212121. The scanning electronic microscopy (SEM) images show irregular shaped parti...... hiện toàn bộ
Photocatalytic H2 production and CO2 reduction on Cu, Ni-doped ZnO: effect of metal doping and oxygen vacancies
Journal of Materials Science: Materials in Electronics - Tập 30 - Trang 18506-18518 - 2019
Ali M. Huerta-Flores, E. Luévano-Hipólito, Leticia M. Torres-Martínez, A. Torres-Sánchez
Cu, Ni-doped ZnO materials were prepared through a fast and simple nital-solution method. XRD and SEM studies confirmed the obtention of the hexagonal brucite structure of ZnO with hexagonal truncated-pyramid morphology. A slight decrease in the cell parameters of ZnO:Cu and ZnO:Ni was observed due to the incorporation in the crystal lattice of Cu2+ and Ni2+. The absorption spectra of ZnO was red ...... hiện toàn bộ
Heterocoagulation method for preparation of composite fluoropolymer particles with core–shell structure for optimized electromagnetic performance
Journal of Materials Science: Materials in Electronics - Tập 32 - Trang 3116-3124 - 2021
Gaoda Zheng, Shiyu Zhang, Weiwei Chu, Jialei Luo, Xiaobing Zuo
Tetrafluoroethylene-hexafluoropropylene copolymer (FEP) plays an important role in 5G communication era. Nevertheless, FeSiCr ferrite as inorganic particles were hardly incorporated in fluoropolymer phase. Heterocoagulation process represents an ideal solution making the inorganic particles disperse uniformly in the fluoropolymer phase. In this work, cetyltrimethylammonium bromide (CTAB) assumes a...... hiện toàn bộ
Synthesis and study of transition metal(Co, Cu, and Ni) substituted ferrites for humidity sensor applications
Journal of Materials Science: Materials in Electronics - Tập 34 - Trang 1-9 - 2023
V. Jagadeesha Angadi, Khalid Mujasam Batoo, Sajjad Hussain, S. O. Manjunatha, Shifa Wang, S. P. Kubrin
Ferrites are a very common commodity in the modern world due to their very strong magnetic permeability, high resistivity, modest permittivity, high saturation magnetization, low power losses, low coercivity, low remanence magnetization, and low power losses. These properties are mainly depending on chemical composition, synthesis method, and other parameter. Further based on these parameter mater...... hiện toàn bộ
