Summary: | Structural properties of
30B2O3-(59-x)TeO2-10MgO-xEu2O3-1Mn3O4 glass are prepared
via melt quenching method. The glass samples are characterized
by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR)
Spectroscopy and Electron Spin Resonance (ESR) Spectroscopy.
The glass nature is confirmed by XRD pattern. FTIR spectra
display a shift in vibrational modes of TeO4 and TeO3 units thus
indicate an alteration in the glass network structure due to an
incorporation of Eu2O3. Influence which varies Eu2O3
concentrations on the structural due to the nature of spin-spin
interaction are determined. Both g value and resonance magnetic
field (Hr) are found to be in the range of (189-198) and (211-226)
Oe respectively. The obtained g value of glass samples will modify
the structural of europium doped magnesium borotellurite glass
due to this presence of manganese oxide nanoparticles (Mn3O4
NPs) which may be useful for developing efficient photonic
devices. |
