Abstract

The spectroscopic properties of Dy3+ ions doped fluoroborate glasses with the composition 39B2O3 + 20ZnO + 20NaF + 20M2O + 1Dy2O3 (where M=Na, K and Ca) have been prepared by melt quenching technique and investigated through XRD,FTIR, absorption and luminescence. The x-Ray diffraction pattern reveals the amorphous nature of the prepared glasses. FTIR results showed the presence of various stretching and bending vibrational modes of the functional groups. From the absorption spectra, the bonding nature of the Dy3+ ions with the ligand field environment is found to be ionic. The variation in hypersensitive transitions with the change in Na, K and Ca content have been studied and discussed. JO intensity parameter have been calculated from absorption spectral intensities and are used to calculate ratiative properties such as the effective bandwidth (Δλeff, nm), transition probability (A), calculated and experimental branching ratios (βR) and stimulated emission cross-section ( ) for the 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions of the Dy3+ ions in prepared fluoroborate glasses.
