Er³⁺ Doped Fluorozirco-Aluminate Glasses

Spectral studies of erbium doped soda lime silicate glasses in visible and near infrared regions

“…This is quite high as compared to those observed in other silicate and phosphate glasses [16,28,37]. Therefore the present glass system is a suitable optical material to be used as broad band fiber amplifier.…”

“…The MD transition contributes to a sharp central peak and ED transition contributes to broader components of this emission band. The stimulated emission cross-section for this transition has been calculated to be 6.30 · 10 À21 cm 2 at 1.54 lm, which is close to those found in phosphate and fluoride glasses [11,16,37]. The dominating factor in determining r p is X 6 parameter.…”

“…In Table 3 we have collected Judd-Ofelt parameters of various types of oxide glasses [12,16,28,29,36,37] for comparison. Fluoride [16] and ZBLAN [38] glasses have also been included.…”

Spectroscopic and radiative properties of Sm3+ doped zinc fluoride borophosphate glasses

“…In this paper, we have studied absorption and fluorescence spectra of four Sm 3+ doped zinc fluoride borophosphate glasses of the composition P 2 [24,25] approach has been applied for the f ↔ f transitions of the RE ion to evaluate Ω λ (λ = 2, 4, 6) parameters, which in turn have been used to calculate various radiative properties [26][27][28] like transition probability, branching ratio, radiative lifetime of the excited state and stimulated emission cross-section of various emission lines because in designing optical devices these data are essentially [29] required. Recently, Koppe [30] has used these radiative properties in developing LEDs highly useful in optical telecommunication for converting electrical pulses into optical pulses in the visible region.…”

“…Among different glass host matrices, fluorophosphates glasses [2][3][4][5][6][7][8][9][10] have distinct advantages over the other glass host matrices. Fluorophosphate glasses are prepared by introducing suitable metal fluorides into phosphate glasses.…”
