“…The PL quantum yields of blue emitting CsCd x Pb 1−x Br 3 in this work are comparable with that of CsPb x Cd 1−x Br 3 colloid PNCs or nanorods (Table S2, Supporting Information). [30,[41][42][43][44][45][46][47] Our results demonstrate that B-site engineering can provide an effective way to tune the PL of PNCs along with enhancing the PL quantum yield. However, the QYs is still low, which may be attributed to the presence of the trapping defects, and there is still plenty of room for the improvement of QYs.…”

Chemical engineering in lead halide perovskite nanocrystals (PNCs) has garnered significant attention for tailoring optoelectronic properties, such as bandgap, quantum yield (QY), and stability. Here, pure blue emissive PNCs in glass by using ultrafast laser are reported. The emission wavelength is tuned in the range from 461 to 520 nm by engineering the chemical composition in the B-site Cd/Pb mix-cation system. The photoluminescence (PL) QY of CsCd x Pb 1−x Br 3 PNCs reaches 13.4% for the pure blue emission at 467 nm, which is twice that of CsPbBr y Cl 3−y PNCs. The pure blue emissive PNCs exhibit remarkable stability when exposed to ultraviolet (UV) radiation, heat, and ethanol solvents. The ultrafast laser print patterns can be encrypted and decrypted for information, which shows great potential for crucial information security applications. These results imply that B-site engineering for lead halide PNCs embedded in glass is effective to tailor the PL spectra and increase the PL QY. The pure blue emissive PNCs hold great potential in the applications of blue and full-color emissive devices.

“…In Ref. [132], borosilicate glasses containing alkali, lead, and halogen elements were prepared, and CsPbX 3 PeNCs were precipitated in the surface layer of the glasses simultaneously during the cesium-potassium ion exchange. CsPbX 3 PeNCs were successfully precipitated on the glass surface through ion exchange in molten cesium nitrate salt.…”

Metal halide perovskites with excellent optical and electronic properties have become a trending material in the current research. However, their limited stability under ambient conditions degrades quality and threatens their potential commercialization as optoelectronic devices. Various approaches are adopted to improve the stability of perovskite nanocrystals (PeNC) while maintaining their advantageous optical properties, particularly strong luminescence. Among different possible improvement strategies, encapsulation of PeNCs within the amorphous glass matrices of inorganic oxides has drawn widespread attention because it ensures high resistance against chemical corrosion and high temperature, thus enhancing their chemical, thermal, and mechanical stability with improved light‐emission characteristics. In this article, two types of materials, namely all‐inorganic metal halide PeNCs and amorphous oxide glasses are briefly introduced, and then the methods are reviewed to fabricate and improve the quality of PeNC@glass composites. These methods are classified into three universal categories: compositional modification, structural modification, and dual encapsulation. In the final part of this review paper, examples of applications of PeNCs@glass composites in light‐emitting devices and displays, data storage and anti‐counterfeiting, lasing, photodetectors and X‐ray detectors, photocatalysis, optical filters, solar concentrators, and batteries are provided.
