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

Photoluminescence properties of Sm3+-doped SFB glasses for efficient visible lasers

“…The lower the symmetry in the vicinity of Sm 3+ ion, the higher will be the value of the Ω 2 parameter. The value of the Ω 2 parameter in the SFB glass is found higher than the earlier reports [11,22,26,27] and lower than Cao-Sb 2 O 3 -B 2 O 3 [28] and borate [29] glasses. A comparison of J-O intensity parameters for different glasses is presented in Table 4.…”

Spectroscopic studies of Sm3+ and Eu3+ co-doped lithium borate glass

“…The assignment of these bands has been made on the basis of data from Refs. [16][17][18] and is listed in Table 1. These bands reveal characteristic Eu 3+ 4f-4f transitions, which are assigned as the transitions from the ground state 7 F 0 and the first excited state 7 F 1 to the higher energy levels.…”

Influence of gold nanoparticles on the up-conversion fluorescence in Sm3+

“…In Fig. 3, the recorded fluorescence excitation spectrum show five well resolved transitions at 360 nm, [27][28][29]. When gold colloids are excited at 595 nm (about 0.504 · 10 15 Hz), two emission peaks take place.…”
