Synthesis and spectral characterizations of chromium doped cadmium borate nanopowder
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Chromium doped Cadmium borate nanopowder was synthesized at room temperature by chemical precipitation method. Metal borates have excellent mechanical properties with good chemical inertness and high stability under high temperature, lightweight, and low thermal expansion coefficients. The prepared nanopowder is characterized by X-ray diffraction (X-RD), Scanning Electron Microscopy (SEM) with EDX, Electron paramagnetic resonance (EPR), Optical studies, Photoluminescence studies and Fourier transform infrared (FTIR) techniques. From XRD powder pattern structure and size of the crystallites are evaluated. SEM images show the stone like morphology of nanopowder. Optical absorption spectrum indicates the distorted octahedral site symmetry of Cr3+ ions. The crystal field Dq and interelectronic repulsion parameters B and C are evaluated. PL spectra indicate clearly that the doping of Cr3+ in the host matrix lead to significant changes in PL intensity. EPR spectrum gives a resonance broad signal at g=1.97 for Cr3+ ions. FT-IR spectrum reveals the characteristic vibrations of Cadmium borate. This unique feature of these materials has widespread a technological importance in the development of tunable solid state lasers and new luminescent materials.
