Problem statement: Systematic series of ZnO-TeO2 glasses with mole fraction 0.10-0.40ZnO content an interval 0.05 were studied to obtain their physical and optical properties.Approach: All the glass samples synthesized by rapid melting quenching method under controlled conditions, while refractive indices (n) measured EL X-02C high precision ellipsometer.The room temperature absorption all determined using Camspec M350 double beam UV-visible spectrophotometer.The infrared (IR) spectra each...
In this paper, thermal treatment procedures were utilised to prepare crystalline nickel oxide semiconductor nanoparticles, derived from an aqueous solution. The solution consists of three compounds, primarily nitrate, polyvinyl pyrrolidine and deionised H2O acting as metal precursor, capping agent solvent, respectively. was made prior the drying, grinding calcination at varying temperature settings up 800 °C. scanning Electron Microscopy (SEM) images allowed a detailed study on morphological...
Abstract A one‐step electrochemical process has been employed to synthesize composite films of polypyrrole/graphene (PPy/GR) by polymerization on indium tin oxide (ITO) from an aqueous solution containing pyrrole monomer, graphene (GO) nanosheets and sodium p ‐toluenesulfonate (NapTS). Thermogravimetric analysis (TGA) confirmed the formation a composite; degradation temperature new hybrid was between those PPy GO. Moreover, bulbous surface almost transparent tissue‐like GO were replaced...
A series of ternary tellurite based glasses [(TeO2)70 (B203)30]100–x [ZnO]x with different compositions ZnO (x= 5 to 30 wt.% in steps wt.%) have been synthesized by melt quenching method. The role the structure was studied IR spectroscopy. FTIR spectra revealed broad, weak and strong absorption bands investigated range wavenumber from 280–4000 cm−1 which associated their corresponding bond modes vibration glass structure. indirect optical band gap direct are 2.08–3.12 1.54–2.36 eV,...
Polypyrrole multi-walled carbon nanotube composite layers were used to modify the gold layer measure heavy metal ions using surface plasmon resonance technique. The new sensor was fabricated detect trace amounts of mercury (Hg), lead (Pb), and iron (Fe) ions. In present research, sensitivity a polypyrrole compared. application nanotubes enhanced accuracy for detecting in an aqueous solution due binding mercury, lead, sensing layer. Hg ion bonded more strongly than did Pb Fe limitation...
Cadmium oxide semiconductor nanoparticles were produced using a water based mixture, incorporating cadmium nitrates, polyvinyl pyrrolidone (PVP), and calcination temperature. An X-ray diffraction (XRD) evaluation was conducted to determine the degree of crystallization nanoparticles. In addition, scanning electron microscopy (SEM) identify morphological features The typical particle sizes dispersal analyzed via use transmission (TEM). findings provided further support for XRD outcomes.
