In this paper, we report the synthesis of tin oxide (SnO2) nanoparticles by co-precipitation technique. The structural, surface morphology, thermal and optical properties of the SnO2 samples were analysed using X-ray diffraction (XRD), High-resolution transmission electron microscopy (HRTEM), Fourier transformed infrared (FTIR) spectrum, thermo gravimetric analysis (TGA/DT...
Recently, the quaternary InGaAsN alloy system has attracted a great deal of attention due to its potential application in devices such as next generation multi-junction solar cells and optoelectronic devices for example laser diodes for optical communications in IR region. In this paper, we have investigated the role of nitrogen on the improvement of optical efficiency in InGaNAs nanostructur...
Analytical techniques employed in modern methods of substance analysis are essentially derived from the foundation science of atomic and molecular absorption spectroscopy which deals with the theory and interpretation of optical spectra (a.k.a. the quantitative and qualitative study of elements and compounds). Some of the familiar technologies which are based in spectroscopy are: Clinical Chemi...
Glow discharge optical emission spectroscopy (GDOES) is a useful technique for qualitative plasma characterization. It also enables depth profiling of solid materials upon exposure samples to energetic positively charged ions from gaseous plasma, providing specifics both surface- and gas-phase collision phenomena that are considered. The early stages developing GDOES the determination surface c...
