Broadband near-infrared emission in Er3+–Tm3+ co-doped bismuthate glasses

Tunable mid‐infrared luminescence from Er3+‐doped germanate glass

“…The Ω λ parameters, together with the values reported for other Er 3+ -doped hosts, are given in Table 2. As shown in Table 1, the calculated values are in good agreement Table 2 that the Ω 2 values of the samples are obviously higher than those of fluoride and tellurite glass (24,29), but lower than that of bismuthate glass (30) 31). In addition, the Ω 6 values of the samples are much lower than the other reported values, as also listed in Table 2, signifying lower local optical basicity (31).…”

A study on the optical, structural, electrical conductivity and dielectric properties of a lithium bismuth germanium tungsten glasses

“…These glasses are attractive to researchers because of their unique structural characteristics, which result from coordination changes in bismuth and germanium. GeO 2 is a typical glass former while Bi 2 O 3 are conditional glass former [10,11]. GeO 2 alone can form * Corresponding author.…”

The spectroscopy investigation of ZnWO4:Tm3+ single crystal

“…3 H 6 transition of Tm 3+ has many practical applications because it locates in the strong absorption peaks of water, which indicate it is an eye-safe wavelength. And so, the $2 lm laser is generally used in the field of surgical procedures as most tissue types [1][2][3][4][5]. The most intensively studied Tmdoped crystals are YAG and YLF.…”
