“…This variation reduced the solubility of lead chalcogenide compounds in glasses, thus forming two sets of PbSe QDs with different sizes, resulting in the appearance of dual‐band absorption and PL, as revealed in Figure k,l. The two emission bands separated by an energy of 110–150 meV and both were from intrinsic excitonic recombination of two sets of PbSe QDs . Instead of being due to the size difference of QDs, dual‐band emission with energy separations of 200 meV was also found to be related to a splitting of the lowest exciton levels in PbS QDs‐doped borosilicate glass with a rather narrow QD size distribution .…”

“…[71] Large full-width at half-maximum (FWHM) of these dual-band PL (≈600 nm) has potentials for broad-band infrared light sources. [70,71] As for QDs-doped fiber amplifier (QDFA), both theoretical simulation and experimental exploration were carried out. Wundke et al reported the optical gain at 1.3 µm of PbS QDs-embedded glass for the first time.…”

of the glass, which can provide a stable environment for QDs. Besides, some new glasses, such as phosphate, germanate, and gallate glasses, are made by replacing Si by P, Ge, and Ga at a slight expense of stability for better transmittance at specific wavelength. Embedding QDs into inorganic glass can secure chemical stability, thermal stability, and mechanical stability, thus providing access to device manufacturing and endurable operation. [15][16][17][18] So far, IIB-VIA, IVB-VIA, and halide perovskite QDs have been successfully incorporated into glass by conventional melt-quenching and subsequent heat-treatment method and their optical properties have been extensively investigated. [18][19][20] Taking advantage of the stability, the applications of QDs-embedded glasses on nonlinear optical devices, [21,22] emitting devices, [15,23,24] and signal amplification in the fiber-optic communication system [3,25] have been explored. Recently, with the outstanding performance of halide perovskite materials in optoelectronic field, the perovskite NCs-doped glasses become a new research hotspot, especially for the applied research on white LED (wLED). For instance, wLED with a luminous efficiency of 50-60 lm W −1 and external efficiency of 20-25% was obtained with perovskite NCs-embedded glass slices as light converters. [24] Particularly, green light-emitting device made by CsPbBr 3 nano crystals (NCs)-embedded glass can realize a luminous efficiency of 118 lm W −1 and an external quantum efficiency of 28.14%. [24] Meanwhile, the luminescence intensity of CsPbBr 3 NCsembedded glass can be maintained above 90% when stored in water for a week or experienced a heating/cooling cycle at 100 °C. [17] QDs-embedded glasses have been studied for several decades. Although there are several review papers for a specific topic such as PbS QDs-doped glasses [26] and QDs-doped glasses for fibers, [27] to our best knowledge, no systematic overview has been made in QDs-embedded inorganic glasses until now. Here, we review the fabrication, luminescent properties, and potential application of QDs-embedded inorganic glasses. We first summarize the preparation methods and growth kinetics of QDs in glasses; we then review the optical properties and application explorations of IIB-VIA, IVB-VIA, and halide perovskite QDs-embedded glasses. Last we propose research directions to overcome the major challenges associated with these glasses for ultimate applications. Quantum dots (QDs)-embedded inorganic glasses combine the outstanding luminescent properties of QDs with the chemical, mechanical, and thermal stability of glasses, overcoming the instability bottleneck of QDs and facilitating their wide and endurable applications such as nonlinear optical devices, light emission, and signal amplification in the fiber-optic communication system. Typical QDs incorporated into glasses include IIB-VIA (e.g., ZnO, CdSe), IVB-VIA (e.g., PbS), and halide perovskite (CsPbBr 3 , et al.) QDs. Here, the preparation methods and growth kinetics of QDs in glasses ...
