“…Transparent glass-ceramic is a very attractive material for mid-infrared (MIR) application because an active crystal phase in the glass matrix can be obtained [13,14,15]. Among the rare-earth ions used as optically active dopants in the glasses and GC, erbium ion can be recommended as a candidate for 3 µm emission due to the transition of 4 I 11/2 → 4 I 13/2 [13,14]. The tellurite glasses show the broadband transmission window (0.35–6 um), the high linear and nonlinear refractive indices, the low phonon energy (~750 cm −1 ) and the high rare-earth solubility.…”

The ErF3-doped oxyfluoride phospho-tellurite glasses in the (40-x) TeO2-10P2O5-45 (BaF2-ZnF2) -5Na2O-xErF3 system (where x = 0.25, 0.50, 0.75, 1.00, and 1.25 mol%) have been prepared by the conventional melt-quenching method. The effect of erbium trifluoride addition on thermal, structure, and spectroscopic properties of oxyfluoride phospho-tellurite precursor glass was studied by differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR), and Raman spectroscopy as well as emission measurements, respectively. The DSC curves were used to investigate characteristic temperatures and thermal stability of the precursor glass doped with varying content of ErF3. FTIR and Raman spectra were introduced to characterize the evolution of structure and phonon energy of the glasses. It was found that the addition of ErF3 up to 1.25 mol% into the chemical composition of phospho-tellurite precursor glass enhanced 2.7 µm emission and upconversion. By controlled heat-treatment process of the host glass doped with the highest content of erbium trifluoride (1.25 mol%), transparent erbium-doped phospho-tellurite glass-ceramic (GC) was obtained. X-ray diffraction analysis confirmed the presence of BaF2 nanocrystals with the average 16 nm diameter in a glass matrix. Moreover, MIR, NIR, and UC emissions of the glass-ceramic were discussed in detail and compared to the spectroscopic properties of the glass doped with 1.25 mol% of ErF3 (the base glass).

“…It indicates that the optical absorption is induced by the rare earth cation of the Er 3+ ions [11,19,24]. The absorption spectra of the PEN-PMN-PT crystals is similar as other Er 3+ -doped ferroelectric materials [25,26]. The UV-VIS-NIR absorption spectra of the PEN-PMN-PT crystals in the wavelength range of 400-1800 nm is shown in Figure 6.…”

“…Finally, the Er 3+ ions return to the ground state 4 I 15/2 with 526 (green), 565 (green) and 665 nm (red) emitted, respectively. Previous reports indicate the ET processes is enhanced with increasing Er 3+ ions concentration because of short distance between neighboring Er 3+ ions [26]. Therefore, Green emissions being significantly enhanced can be explained by the intense ET process that led to populated 4 I 11/2 state.…”

New ferroelectric crystals Pb(Er1/2Nb1/2)-Pb(Mg1/3Nb1/3)O-PbTiO3 (PEN-PMN-PT) were grown by using the flux method. Phase structure of the crystals was described by the X-ray diffraction analysis. Dielectric, ferroelectric and optical properties of the PEN-PMN-PT crystals were investigated systematically. Higher Curie temperature (Tc ~ 291 °C) and larger coercive field (Ec ~ 17.6 kV/cm) for the 40PEN-13PMN-47PT can be obtained, respectively, compared with those of the PMN-PT. Moreover, strong green and red emissions can be excited by using the 980 nm laser. The PEN-PMN-PT crystals with these performances have some promising applications in the electromechanical and optical devices.

“…Rare earth ions doped glass fibers that exhibit laser emission around ~2.0 µm have been paid considerable attention due to their potential applications in eye safe laser radar, atmosphere pollution monitoring, measurement of water vapor and biomedicine, etc [1][2][3][4][5]. A number of experiments have proved that Tm 3+ and Ho 3+ perform well in achieving 2.0 µm laser.…”

Structural and fluorescence properties of Ho 3+ /Yb 3+ co-doped germanosilicate glasses have been modified by tailoring the composition using lanthanide additive Lu 2 O 3. Raman spectra and X-ray Photoelectron spectra reveal that the addition of Lu 2 O 3 can change the structure by increasing non-bridging oxygens (NBO) in this glasses. Meanwhile, an improved thermal stability (∆T: from 110 to 187 ˚C) has also been obtained via Lu 3+ 'lanthanide contraction'. Futhermore, the positive effect of changed glass structure gives excellent fluorescence properties by the decreasing cross relaxation process which are proved by the experimental upconversion, near-infrared and mid-infrared fluorescence spectra. Additionally, a double enhancement of a 2.0 µm emission has been achieved successfully in this silica-germanate glass with 7 mol% Lu 3+ addition, which possesses a larger emission cross section (4.41 × 10 −21 cm 2) at 2022 nm. These results indicate that the optimized emission of Ho 3+ for optical fiber laser can be achieved by tuning the glass structure using lanthanide additive Lu 2 O 3 .
