From these spectra we have demonstrated the occupancy of two nonequivalent positions by the Er 3ϩ ion in the sample. Time decay measurement, emission versus temperature analysis, and selective site excitation were made to confirm our conclusion. From emission versus temperature for 4 S 3/2 → 4 I 15/2 transitions and from the selective site excitation, we were able to select the group of lines that belong to each site. In this article, we present a table with the energy-level values for the ground 4 I 15/2 and the excited 4 S 3/2 multiplets of the Er 3ϩ ion in each site.

Stark splitting of the ground state of Er3+ in fluorozirconate glass at low temperature

“…4 we observe that the emission corresponding at T labeled T 4 displays a tail at the high energy region. This can be explained by an emission of the upper level of the 4 S 3/2 populated by decay from the 2 H 9/2 multiplet because this upper level cannot be populated by thermal energy in this temperature [16]. The population of the 4 I 13/2 is obtained by the same process reported by Bigot et al [5].…”

“…At T = 2 K, only the lower level of the 4 S 3/2 multiplet became populated and it is expected eight emission lines in the 4 S 3/2 ? 4 I 15/2 transition [16] (Fig. 1).…”

“…2 suggest that there is just one kind of symmetry around the Er 3+ ions in the ZBLAN matrix although it is not possible to predict the coordination number or the type of symmetry. The existence of ions in other environments should originate other eight-line sets in the emission spectrum [15,16]. From Fig.…”

Crystal-Field Analysis of the Ce3+ Spectrum in YAlO3 Single Crystals

“…Recently, more and more interest is devoted to trivalent rare-earth (RE 3+ ) doped different host crystals due to their potential device applications as optoelectronic compounds [1,2]. Many optical studies have been reported: sharply structured photoluminescence bands resulting from internal electronic configuration 4f n transitions of the rare-earth ions were observed [1].…”

Spectral of the ZBLAN:Er3+ system at low temperature

“…The crystalline interaction breaks the degeneracy of the Er 3+ Kramer's ion and each multiplet of this ion splits into (2J + 1)/2 Stark components [1,2]. The 4 S 3/2 and 4 l 15/2 multiplets splits in two and eight components, respectively.…”
