M. Sundararajan,L. John Kennedy +1 more
TL;DR: In this paper, high resolution scanning electron microscopy (HR-SEM), energy dispersive X-ray (EDX) analysis, UV-visible diffuse reflectance spectroscopy, photoluminescence (PL) spectrograph, Fourier transformed infrared (FT-IR), and vibrating sample magnetometry.
Journal ArticleDOI
Structural, optical and magnetic properties of Zn1−xMnxAl2O4 (0 ⩽ x ⩽ 0.5) spinel nanostructures by one-pot microwave combustion technique
TL;DR: In this paper, structural, vibrational, morphological, optical and magnetic properties were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), high resolution scanning electron microscopy (HR-SEM), UV-visible diffuse reflectance spectrograph (DRS) and photoluminescence (PL) spectrograms, and vibrating sample magnetometry (VSM).
Journal ArticleDOI
One step phytosynthesis of highly stabilized silver nanoparticles using Piper nigrum extract and their antibacterial activity
TL;DR: In this paper, a phytosynthesis of highly stabilized silver nanoparticles (AgNPs) had been produced by using the extract of Piper nigrum (black pepper) as a reducing and a capping agent in aqueous medium, without the addition of any other chemicals.
Journal ArticleDOI
Facile microwave assisted combustion synthesis, structural, optical and magnetic properties of La2? xSrxCuO4 (0???x ? 0.5) perovskite nanostructures
TL;DR: In this article, the structural, optical, morphological, and magnetic properties were studied by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance spectra (DRS), scanning electron microscopy (SEM) and energy dispersive Xray analysis (EDX), photoluminescence (PL) and vibrating sample magnetometer (VSM) techniques.
Journal ArticleDOI
Comparative studies on influence of morphology and La doping on structural, optical, and photocatalytic properties of zinc oxide nanostructures
TL;DR: In this paper, a simple low temperature co-precipitation method was developed to synthesize ZnO nanomaterials with different morphologies such as nanoflakes, spherical nanoparticles (SNPs), and nanorods.
