Abstract

nVO2+ doped SrMg2(PO4)2 nanopowder was synthesized by using solid state reaction (SSR) technique. Various experimental techniques have been performed on prepared sample. XRD analysis has revealed that prepared nanopowder is in monoclinic phase. The average crystallite size, micro strain and dislocation density evaluated and make an analogy with W-H plot method. SEM micrographs shows that agglomerated stone like structure and EDS spectrum shows elemental compositions of synthesized sample. FTIR spectrum shows vibrational bands associated with phosphate, P-O-H and hydroxyl ions. Crystal field (Dq) and tetragonal field (Ds & Dt) parameters were determined by optical absorption. Energy gap of material evaluated by using Kubelka-Munk plot. Spin-Hamiltonian parameters evaluated using EPR data. The obtained values from Optical absorption and EPR studies suggests that dopant ion exhibited octahedral site with tetragonal compression in host lattice. PL spectrum exhibited emission bands in visible area. The calculated chromaticity coordinates located at white region in CIE diagram. CRI and CCT parameters are evaluated. These results are indicating that the prepared nano powder is suitable for white LEDs and display devices.
