Article Synopsis
  • The study successfully synthesized undoped and La-doped NiCrO nanorods using a solution-based method and assessed their optical properties using DRS and PL spectroscopy.
  • Structural characterization was performed through FTIR and XRD techniques, while HRTEM analysis showed the connection of NiCrO nanorods to nanoparticles.
  • Findings indicated that factors like reaction time, band gap energy, and particle size were significantly influenced by altering La concentration, with average particle sizes for the samples ranging from 16 to 24 nm.

Among the many industrially important zeolites, mordenite is found to be interesting because of its unique and exceptional physical and chemical properties. Mordenite (high silica zeolite) is generally prepared by the hydrothermal method using TEA cations. TEA cations are the best templating agent, though they can create a number of issues, for instance, generating poison and high manufacturing cost, wastewater contamination, and environmental pollution.

Research on CdSe/ZnS core-shell quantum dots (QDs) was synthesized by a chemical route using bio-conjugated organic amino acid (L-Cysteine). The structural, morphological, and optical properties of the nanocrystal powder samples were analyzed using various characterization techniques. The diameter of the resulting QDs was about 3 nm with uniform size distribution.

In the present study, ZnO nanoparticles (ZNPs) and nanoflakes (ZNFs) were prepared by conventional combustion method and microwave combustion method, respectively. The structural phase and morphology were investigated by using X-ray diffraction (XRD), high resolution scanning electron microscopy (HR-SEM) and high resolution transmission electron microscopy (HR-TEM). The crystallite size was calculated using Scherrer formula, and it lies in the range of 20-21 nm for ZNFs and 23-28 nm for ZNPs.
