Cytotoxicity effects of synthesized ZnO and Zn0.97X0.03O (X=Li, Na, and K) nanoparticles by the gelatin-based sol-gel method

Surface related and intrinsic exciton recombination dynamics in ZnO nanoparticles synthesized by a sol-gel method

Intense visible emission from ZnO/PAAX (X = H or Na) nanocomposite synthesized via a simple and scalable sol-gel method

Intense visible nano-emitters are key objects for many technologies such as single photon source, bio-labels or energy convertors. Chalcogenide nanocrystals have ruled this domain for several decades. However, there is a demand for cheaper and less toxic materials. In this scheme, ZnO nanoparticles have appeared as potential candidates. At the nanoscale, they exhibit crystalline defects which c...

Structure and luminescence of sol-gel synthesized anatase nanoparticles

Two samples of mesoporous anatase nanoparticles, prepared by the sol-gel method, were characterised by Cs-corrected high resolution transmission electron microscopy (HRTEM), X-ray powder diffraction (XRD) and Raman spectroscopy. Statistical evaluation of TEM data showed an average diameter of these crystallites of 8.8 nm and 11.1 nm, respectively. Optical spectroscopy by cathodoluminescence (CL...

Characterization of Structural, Optical and Hydrophilicity properties of TiO2 Nano-Powder Synthesized by Sol-Gel Method

In this paper, titanium dioxide nano-particles were synthesized by sol-gel method in acidic atmosphere. The microstructure, morphology, optical band gap, and hydrophilicity of the sample were studied. Optical band gap of titanium dioxide was probed via Diffuse Reflectance Spectra (DRS) and contact angle (CA) was measured to investigate surface activity. XRD analysis was used to study crys...

Synthesis and Characterization of ZnO Nanoparticles Using Sol-gel Process

In the Present work structural, morphological and compositional properties of ZnO nanopowders synthesized using Zinc nitrate and NaOH using sol-gel process were reported. The synthesized nanopowders were further analyzed using X-Ray Diffraction (XRD), Scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopic characterizations. Crystalline size and Lattice strain det...

Structural and Optical Properties of Sr-Modified Bismuth Silicate Nanostructured Films Synthesized by Sol Gel Method

In this work, the effects of strontium addition on the structure and optical properties of nanostructured bismuth silicate (Bi4Si3O12) thin films prepared via sol-gel were studied. At first, different sols containing the optimum ratio of precursors were synthesized, and then, the prepared sols were coated on the substrate via dip coating. The dip coated samples were dried at 100oC and, in order...
