“…Raw materials of B 2 O 3 , SiO 2 , ZnO, Cs 2 CO 3 , PbBr 2 , and NaBr were mixed and then melted at 1200 °C for 10 min with a cover preventing the volatilization of low melting point compounds. [21,29,32] After pouring the melt into a mold, the precursor glass was prepared. The precursor glass was well polished and then the CsPbBr 3 QDs were precipitated at 450 °C for 3 h.…”

“…[19] The success of optical amplification stimulates the exploration of the crystallization of CsPbX 3 QDs in the appropriate glass composition. Despite being a successful alternative for optical storage and light-emitting diodes, [21,[29][30][31][32][33] the crystalized CsPbX 3 QDs in a selected glass have many defect states, which hinders their application to laser/incoherent diode, fiber laser as well as optical amplifier chips. Therefore, the success of amplified spontaneous emission based on CsPbX 3 QDs in an appropriate glass composition will open new horizons and huge opportunities for the practical application of glass ceramics as well as metal halide perovskites.…”

densities, long carrier diffusion lengths, high photoluminescence quantum yield (PLQY), tunable direct bandgap, and low Auger recombination rate. [11][12][13][14] With these unique properties, a tide of intensive research on organic-inorganic halide perovskite-based amplified spontaneous emission (ASE)/laser, including but not limited to thin-film, has been conducted with the excitation of optical pumping sources. [15,16] In addition to the aforementioned medium, colloidal nanocrystals of cesium lead halide perovskites have also drawn tremendous attention due to their high stability upon exposure to optical pumping, thermal stress, and moisture. [17] At the same time, the quantization of electron energy levels of nanocrystals also contributes to narrow emission width. Since the first report on ASE from CsPbBr 3 nanocrystals, all-inorganic perovskites nanocrystals (CsPbX 3 , X = Cl, Br, I) have been dramatically developed. In particular, bandgap energies are precisely and continuously controlled through compositional regulation (mixed halide Cl/Br and Br/I) as well as quantum-size effects. [17] Another key practical advantage of CsPbX 3 nanocrystals is the easy realization of emission covering a blue-green spectral region (410-530 nm) through facile synthesis. [18] As a comparison, only an extremely small (≤5 nm) size for common metal chalcogenide nanocrystals such as CdSe can contribute to being an approach to the blue-green region; even then, the PLQY is rather low (≤5%) owing to the mid-gap trap states. [17] ASE wavelength is also tunable from visible range to near-infrared spectral range by integrating the facile processability with the merits of quantum confinement. [17] Further, CsPbX 3 nanocrystals are easy to mix with other optoelectronic materials (polymers, optical glass, and nanomaterials) for further adjustments of optical properties and application in various environments.Optical glass is an excellent medium for optical storage, amplification, and waveguide used in society, industry, and scientific research, mainly due to its unequaled optical transparency as well as prominent mechanical, chemical, and thermal resistance. [1,9,[19][20][21][22][23] The improvement and optimization of optical property are achievable by the introduction of homogeneously distributed phosphor particles/semiconductor nanocrystals in a glass matrix via embedment and/or crystallization (nucleation and crystal growth). [9,[19][20][21] In addition, the phosphors/nanocrystals inside the glass have high chemical and physical stability owing to the insulation of glass to the external moisture,The diverse optoelectronics systems can provide interesting design inspiration for photonics devices, ranging from optical modulators to light-emitting displays. With the increasing applications and requirements of optical interconnect in complex environments, an essential operation is increasingly being pursued to exploit the consolidation of various merits of basic components. Here, an optical gain from monodisperse CsPbBr 3 quantum dots cr...

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.

“…Doping of semiconductor QDs with impurities can affect the various properties of host materials like high photoluminescence (PL) quantum yield (QY), long luminescence excited state lifetimes, large Stokes shis, thermally stable luminescence, and tunable emission colors. [19][20][21][22] Doping can also affect the crystal growth of semiconductor QDs as the surface energy is changed. Therefore, the growth and shape of the QDs may be affected.…”
