Optical Properties of Dy3+ and Ce3+ in Borate Glass

Tran, Ngoc
Spectroscopic properties of Dy3+ and Ce3+ ions doped alkali metal borate glasses (70-x-y)B2O3.15Li2CO­­3.15Na2CO3.xDy2O3 and yCeO2 (BLN:Dy,Ce) fabricated by melting method have been studied. Energy transfer from the absorption and fluorescence center has been discussed. Judd–Ofelt (J-O) theory has been used to evaluate various spectroscopic properties such as oscillator strengths (fexp, fcal), intensity parameters Ωl(l=2,4,6), spontaneous transition probabilities (AR), radiative life times (tR) and luminescence branching ratios (σexp, σR). The cross-relaxation mechanism was discussed for BLN glass.
