Judd–Ofelt analysis of the Er3+(4f11) absorption intensities in phosphate glass: Er3+, Yb3+

Abstract: A spectroscopic Judd–Ofelt investigation has been performed on Er3+ in the doubly doped phosphate glass:Er3+, Yb3+ in order to assess its potential as a laser system. The standard Judd–Ofelt model was applied to the room-temperature absorption intensities of Er3+(4f11) transitions to determine the intensity parameters: Ω2=6.28×10−20 cm2, Ω4=1.03×10−20 cm2, and Ω6=1.39×10−20 cm2 in the phosphate glass host. The intensity parameters are used to determine the radiative decay rates (emission probabilities of trans… Show more

“…In Samples B and C, the experimentally deduced A r almost agrees with the theoretically estimated values [34,35] which was obtained by using the Judd-Ofelt parameters Ω t (t = 2, 4, 6) in (Er x ,Sc 1−x ) 2 O 3 transparent ceramics with x = 0.003 [36]. On the other hand, a larger A r was observed in Sample A, and it suggests the increase in the effective transition dipole moment.…”

“…The observed bands are attributed, respectively, to the multiplets 4 [24][25][26][27][28]. The spectroscopic quality factor χ =  4 / 6 is approximately 0.37 which is in the range of It is obvious that the branching ratio and the radiative lifetime are two critical parameters that can predict the possibility of laser emission.…”
