Spectral investigations of Mn2+ doped Zn3(BO3)2 nanopowder

Mn2+ doped Zn3(BO3)2 nanopowder has been prepared by simple chemical solution method and characterized by powder XRD, SEM with EDS and several spectroscopic techniques. From powder XRD pattern, the crystal structure belongs to monoclinic and the average crystallite size is evaluated. SEM images showed the surface morphology of as prepared samples. Optical absorption spectrum exhibited the characteristic bands of Mn2+ ions in octahedral site symmetry. EPR spectrum showed resonance signal around g = 2.0 and from this bonding nature between the doped Mn2+ ions and its ligands is also determined. Room temperature Photoluminescence spectrum showed UV emission band around 302 under the photon excitation wavelength of 263 nm. FT-IR spectrum shows the characteristic vibration bands of metal oxide and borate molecules.
