Abstract

Cr3+ ion doped ZnCdO nanopowder was synthesized by chemical solution method. Structural (Xray diffraction, surface morphology and energy dispersion), different spectroscopic studies like FT-IR, EPR, Optical and PL were performed on the prepared nanopowders. From the XRD pattern, it was confirmed that the crystalline size of the nanopowder was at nanoscale range. The morphological surface of the powder was analyzed by SEM. FT-IR showed the trademark assimilation groups identified with the metal oxides and additionally other natural particles. EPR spectrum exhibited characteristic Cr3+ ion resonance signal at g = 1.98. By connecting EPR and optical information, the holding parameters have been resolved. From the optical absorption studies, the assimilation groups are assessed. Photoluminescence studies showed that the outflow groups are in UV and blue area. These parameters recommended that Cr3+ ions are in octahedral site symmetry with covalent bonding nature.
