“…Therefore, the Ni 2+ ions should be embedded in the ZnGa2O4 nanocrystals after the heat treatment. It was reported in the literature that blue, brown, and yellow-green glass colors are observed in the case of 4 Ni 2+ , 5 Ni 2+ , and 6 Ni 2+ coordination, respectively [42]. Besides, after heat treatment at 650 °C for 5 h, UV absorption is red shifted and background absorption is slightly higher in comparison to as-melted glass.…”

“…For this reason, the possible expansion of emission bands in erbium-doped fiber amplifiers (EDFA) in different ways is a hot topic [1]. In particular, the following co-doping system of rareearth ions (RE) has been proposed, including: Er 3+ /Tm 3+ , Pr 3+ /Er 3+ , Er 3+ /Tm 3+ /Pr 3+ , Yb 3+ /Er 3+ /Tm 3+ and others [2][3][4][5]. However, the main general problem in co-doping systems is the narrowing of 4f-4f transitions and unwanted energy transfer mechanism between RE ions which strongly limits the effective emission in the near-infrared spectral range.…”

An investigation of the structural and luminescent properties of the transparent germanate glass-ceramics co-doped with Ni2+/Er3+ for near-infrared optical fiber applications was presented. Modification of germanate glasses with 10–20 ZnO (mol.%) was focused to propose the additional heat treatment process controlled at 650 °C to obtain transparent glass-ceramics. The formation of 11 nm ZnGa2O4 nanocrystals was confirmed by the X-ray diffraction (XRD) method. It followed the glass network changes analyzed in detail (MIR—Mid Infrared spectroscopy) with an increasing heating time of precursor glass. The broadband 1000–1650 nm luminescence (λexc = 808 nm) was obtained as a result of Ni2+: 3T2(3F) → 3A2(3F) octahedral Ni2+ ions and Er3+: 4I13/2 → 4I15/2 radiative transitions and energy transfer from Ni2+ to Er3+ with the efficiency of 19%. Elaborated glass–nanocrystalline material is a very promising candidate for use as a core of broadband luminescence optical fibers.

“…To meet the demands of WDM systems, it has become crucial to develop ultra-broadband fiber amplifiers that covers O-band to U-band communication window. 57 However, due to the NIR loss edge, conventional silica-based glass fibers are limited to wavelengths shorter than 2.4 μm. This limitation can be overcome by using non-silica glasses such as fluoride, tellurite, and chalcogenide glasses, which have low melting temperatures than silicate glass and are often multi-component glasses.…”

The inherent properties of heavy metal oxide glasses have led to their widespread applications in various domains including lasers, optical fibers, optoelectronics, and radiation shielding materials. Tellurium oxide and bismuth oxides are conditional glass forming heavy metal oxides which, when combined, suitably yield significant improvement in the whole system. Lower phonon energy of tellurite helps in aiding broader transmission and lasing properties, while the ability of bismuth ions to reside in various valence states aids in incorporation of optically active rare earth ions in these glasses. The near infrared emission characteristic of bismuth ions could be improved by co-doping with rare earth ions to improve the emission and consequently their applications as photonic devices. Higher density of these oxides helps in increasing the radiation shielding ability, thereby making them suitable replacement materials for lead based toxic compounds.
