“…We are aware of the requirements for the fabrication of cylindrical or planar optical fibers (in bulk or fiber optics)—a larger number of glasses (20 g) are needed. Despite this, an exothermic (crystallization) peak at the 395 °C ΔT parameter (ΔT = Tx − Tg = 88 °C) confirmed the high thermal stability of the glass, which allows for using glasses in an optical fiber drawing process [ 26 ]. As someone may not agree with that stability parameter is an indicator for drawing (our team who deal with fiber drawing is not always familiar with this concept), it is known that fluoroindate glasses can be drawn into optical fibers [ 15 , 16 ].…”

“…Spectroscopic properties of the singly Ho 3+ -doped fluoroindate glasses in MID-IR spectral range have been reported before [ 22 ]. It should be noted that infrared luminescence studies of RE-co-doped fluoroindate glasses are practically limited to the Er 3+ /Tm 3+ Er 3+ /Yb 3+ , Tm 3+ /Ho 3+ , and Er 3+ /Ho 3+ [ 23 , 24 , 25 , 26 ].…”

This work reports on the fabrication and analysis of near-infrared and mid-infrared luminescence spectra and their decays in fluoroindate glasses co-doped with Yb3+/Ho3+. The attention has been paid to the analysis of the Yb3+→ Ho3+ energy transfer processed ions in fluoroindate glasses pumped by 976 nm laser diode. The most effective sensitization for 2 μm luminescence has been obtained in glass co-doped with 0.8YbF3/1.6HoF3. Further study in the mid-infrared spectral range (2.85 μm) showed that the maximum emission intensity has been obtained in fluoroindate glass co-doped with 0.1YbF3/1.4HoF3. The obtained efficiency of Yb3+→ Ho3+ energy transfer was calculated to be up to 61% (0.8YbF3/1.6HoF3), which confirms the possibility of obtaining an efficient glass or glass fiber infrared source for a MID-infrared (MID-IR) sensing application.

“…Similar to our previous works for fluoroindate glasses 17 , 18 , the appropriate laser equipment was used for measurements of luminescence spectra and decay curves. The laser system consists of PTI QuantaMaster QM40 spectrofluorimeter, optical parametric oscillator (OPO), Nd:YAG laser (Opotek Opolette 355 LD), double 200 mm monochromators and multimode UVVIS PMT (R928) and Hamamatsu H10330B-75 detectors, and PTI ASOC-10 [USB-2500] oscilloscope.…”

“…These improved spectroscopic parameters are necessary for signal amplification in telecommunication and laser technology. Some recently published works for fluoroindate glass clearly indicate that a logical extension of Er 3+ -doped systems would be the addition of other rare earth ions such as Tm 3+ or Ho 3+ ions 17 , 18 . The interesting results for fluoroindate glasses co-doped with Ho 3+ /Tm 3+ and Ho 3+ /Nd 3+ ions 19 , 20 emitting near-infrared and mid-infrared radiation at 2 μm and 3.9 μm under direct excitation (888 nm or 808 nm) have been also well presented and discussed in details.…”

Fluoroindate glasses co-doped with Pr3+/Er3+ ions were synthesized and their near-infrared luminescence properties have been examined under selective excitation wavelengths. For the Pr3+/Er3+ co-doped glass samples several radiative and nonradiative relaxation channels and their mechanisms are proposed under direct excitation of Pr3+ and/or Er3+. The energy transfer processes between Pr3+ and Er3+ ions in fluoroindate glasses were identified. In particular, broadband near-infrared luminescence (FWHM = 278 nm) associated to the 1G4 → 3H5 (Pr3+), 1D2 → 1G4 (Pr3+) and 4I13/2 → 4I15/2 (Er3+) transitions of rare earth ions in fluoroindate glass is successfully observed under direct excitation at 483 nm. Near-infrared luminescence spectra and their decays for glass samples co-doped with Pr3+/Er3+ are compared to the experimental results obtained for fluoroindate glasses singly doped with rare earth ions.

Crystalline α‐Gd2(MoO4)3 is synthesized by sintering at 800 °C using a coprecipitation method to prepare the precursor. The resulting α‐Gd2(MoO4)3 displayed a monocrystalline structure with a strong main peak (‐221) in the X‐ray diffraction signal. To develop a light‐emitting material, rare earth ions are added during synthesis. By doping with Tb3+ and Eu3+, the Gd2(MoO4)3 down‐conversion phosphor shows potential for use in UV–LED chips, counterfeit money prevention, and fingerprint identification. Additionally, co‐doping with [Er3+]/[Yb3+] and [Ho3+]/[Yb3+] ions produce green and red emissions when applied to a 980 nm LED chip, useful for anti‐counterfeit ink. The magnetic properties of gadolinium are leveraged to confirm magnetic resonance imaging luminescence. A flexible composite for heat detection and explored various applications for its use is also developed.
