“…Several studies showed that the heat-treatment in zinc-tellurite glass systems containing Ag NPs is limited because of easy crystallization of ZnTeO 3 [22]. Conversely, the tellurite-tungsten-lanthanum glasses are found to be more stable [23,24].…”

Perovskites have been studied because of their adjustable wavelength range, high color purity, and wide color gamut. However, they still face some problems such as poor stability and insufficient infrared luminescence. The perovskite glass can improve the stability and luminescence properties of the perovskite. In this paper, a highly stable CsPb 1−x Er x Br 3 −ZBLAN fluoride glass with mid-infrared and visible light emission was prepared. The ZBLAN fluoride glass has good inertness, which can improve the stability of the CsPb 1−x Er x Br 3 perovskite. The CsPb 1−x Er x Br 3 −ZBLAN fluoride glass can prevent the perovskite from being destroyed by water, oxygen, and laser. The Er 3+ replaces Pb 2+ to bond with Br − to become the luminescent center of the CsPb 1−x Er x Br 3 −ZBLAN perovskite glass, which extends the luminescence to the mid-infrared region. In addition, its luminescent intensity is significantly higher than those of the ZBLAN− Er glass and CsPb 1−x Er x Br 3 perovskite. After irradiation with a 365 nm UV lamp for 13 h, the luminescence intensity of the CsPb 1−x Er x Br 3 −ZBLAN perovskite glass decreases only by 10%. The EDS spectrum shows that the elements of the CsPb 1−x Er x Br 3 perovskite are uniformly distributed in the glass matrix. The X-ray diffraction spectrum shows that the sample has both the CsPb 1−x Er x Br 3 perovskite phase and the glass phase. This indicates that CsPb 1−x Er x Br 3 is well crystallized in the ZBLAN glass matrix. The three parameters calculated by the Judd−Ofelt theory show that the CsPb 1−x Er x Br 3 perovskite can increase the covalency and asymmetry around the rare earth ion Er 3+ . The transmission electron microscope can clearly see the morphological structure of the CsPb 1−x Er x Br 3 perovskite in the ZBLAN glass matrix. The infrared Fourier transform spectroscopy shows that the sample has lower phonon energy. This proves that the sample has good infrared luminescence characteristics. Finally, the visible and infrared light sources were prepared. Under the irradiation of the 365 nm ultraviolet lamp and 980 nm laser, the perovskite glass produces green light and infrared emission.

“…However, the reported ~4 μm emission from Ho 3+ ions is subject to revision since harmonic peak of Ho 3+ : ~2 μm emission arises exactly at ~4 μm and it is very difficult to eliminate this harmonic peak unless one suppresses the ~2 μm emission by using a proper high pass IR cut-on filter >2 μm. Also, there is no mention of filters used while recording the ~4 μm MIR emission in their report 13 14 .…”

“…In this contest, tellurite glasses (transparency upto ~6 μm) have been under strenuous study because of their advantages over fluoride and chalcogenide based glasses. There are few reports on ~2.7 μm emission from Er 3+ ions 8 9 10 , ~2.8 μm, ~4 μm from Ho 3+ ions 11 , 12 , 13 , 14 and ~2.9 μm, ~3.3 μm from Dy 3+ ions 15 16 when doped in tellurite glasses. However, the reported ~4 μm emission from Ho 3+ ions is subject to revision since harmonic peak of Ho 3+ : ~2 μm emission arises exactly at ~4 μm and it is very difficult to eliminate this harmonic peak unless one suppresses the ~2 μm emission by using a proper high pass IR cut-on filter >2 μm.…”

The foremost limitation of an oxide based crystal or glass host to demonstrate mid- infrared emissions is its high phonon energy. It is very difficult to obtain radiative mid-infrared emissions from these hosts which normally relax non-radiatively between closely spaced energy levels of dopant rare earth ions. In this study, an intense mid-infrared emission around 2.9 μm has been perceived from Ho3+ ions in Yb3+/Ho3+ co-doped oxide based tellurite glass system. This emission intensity has increased many folds upon Yb3+: 985 nm excitation compared to direct Ho3+ excitations due to efficient excited state resonant energy transfer through Yb3+: 2F5/2 → Ho3+: 5I5 levels. The effective bandwidth (FWHM) and cross-section (σem) of measured emission at 2.9 μm are assessed to be 180 nm and 9.1 × 10−21 cm2 respectively which are comparable to other crystal/glass hosts and even better than ZBLAN fluoride glass host. Hence, this Ho3+/Yb3+ co-doped oxide glass system has immense potential for the development of solid state mid-infrared laser sources operating at 2.9 μm region.
