“…Going on further, Machado et al reported the synthesis of co-doped Er 3+ /Yb 3+ /Ce 3+ tellurite glasses containing copper (Cu) NPs. 41 The effect of the NPs on the optical properties was investigated, and it was revealed that Cu NPs enhanced the Er 3+ emission by 47%. Also, a 50% increase was noted in the lifetime of the transition 4 I 13/2 → 4 I 15/2 .…”

“…For example, the 3.9 μm and 4.1 μm mid-infrared fluorescence emissions were analyzed in Ho 3+ /Yb 3+ /AgNPs doped TeO 2 –ZnO–WO 3 –La 2 O 3 –BaF 2 glass system [ 16 ]. The infrared and up-conversion emissions of Er 3+ /Yb 3+ /Ce 3+ co-doped tellurite glasses with copper nanoparticles (NPs) were also studied [ 17 ]. The obtained results have shown that the presence of the CuNPs enhanced Er 3+ emission at 1.55 μm and increased the lifetime of the Er 3+ : 4 I 13/2 → 4 I 15/2 transition by 50% [ 17 ].…”

“…Moreover, tellurite and germanate glasses have also been investigated as suitable hosts for metal or semiconductor nanoparticles (NPs) [16][17][18][19]. For example, the 3.9 µm and 4.1 µm mid-infrared fluorescence emissions were analyzed in Ho 3+ /Yb 3+ /AgNPs doped TeO 2 -ZnO-WO 3 -La 2 O 3 -BaF 2 glass system [16].…”

The gains enhancement and an increase in the emitted intensity of RE ions because of the presence of the nanoparticles were observed in the germaniate systems [18,19].…”

Investigation of the TeO2/GeO2 Ratio on the Spectroscopic Properties of Eu3+-Doped Oxide Glasses for Optical Fiber Application

This study presented an analysis of the TeO2/GeO2 molar ratio in an oxide glass system. A family of melt-quenched glasses with the range of 0–35 mol% of GeO2 has been characterized by using DSC, Raman, MIR, refractive index, PLE, PL spectra, and time-resolved spectral measurements. The increase in the content of germanium oxide caused an increase in the transition temperature but a decrease in the refractive index. The photoluminescence spectra of europium ions were examined under the excitation of 465 nm, corresponding to 7F0 → 5D2 transition. The PSB (phonon sidebands) analysis was carried out to determine the phonon energy of the glass hosts. It was reported that the red (5D0 → 7F2) to orange (5D0 → 7F1) fluorescence intensity ratio for Eu3+ ions decreased from 4.49 (Te0Ge) to 3.33 (Te15Ge) and showed a constant increase from 4.58 (Te20Ge) to 4.88 (Te35Ge). These optical features were explained in structural studies, especially changes in the coordination of [4]Ge to [6]Ge. The most extended lifetime was reported for the Eu3+ doped glass with the highest content of GeO2. This glass was successfully used for the drawing of optical fiber.
