| Description | An investigation of the structural and luminescent properties of the transparent germanate glass-ceramics co-doped with $Ni^{2+}/Er^{3+}$ 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 $ZnGa_{2}O_{4}$ 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 $(λ_{exc}$ = 808 nm) was obtained as a result of $Ni^{2+}$:$ $^{3}T_{2}$(^{3}$F) →$ $^{3}A_{2}$(^{3}$F) octahedral $Ni^{2+}$ ions and $Er^{3+}$:$ $^{4}$I_{13/2}$ →$ $^{4}$I_{15/2}$ radiative transitions and energy transfer from $Ni^{2+}$ to $Er^{3+}$ with the efficiency of 19%. Elaborated glass–nanocrystalline material is a very promising candidate for use as a core of broadband luminescence optical fibers. |
