(Wiley-VCH Verlag GmbH, 2025) Samiei, Sadaf; Lin, Jidong; Soheyli, Ehsan; Nabiyouni, Gholamreza; Chen, Daqin
Encapsulation of perovskite nanocrystals (PeNCs) within metal oxide glasses and fabrication of PeNCs@glass composites has emerged as a transformative approach to enhance the stability and functionality of these promising luminescent materials. This review comprehensively examines the current state of research on encapsulation techniques, highlighting their effectiveness in preserving the structural integrity, and optical properties of PeNCs. The advantages and mechanisms by which metal oxide glasses mitigate the degradation of PeNCs are discussed and the tunable properties of metal oxide glass structures for optimizing the photoluminescence and quantum efficiency of encapsulated PeNCs are explored. The review further explores the various experimental techniques for characterizing composites made by nanoscale extreme crystalline species within the short-range ordered (amorphous) microstructures. As the ultimate aim of any advanced material for commercialization, diverse optoelectronic devices of these encapsulated systems, emphasize the potential for improved device performance and longevity. Finally, key challenges and future directions in the field are identified, including the need for scalable fabrication methods and the exploration of novel glass compositions to enhance the encapsulation efficacy. This review aims to provide a comprehensive overview of the advancements in the encapsulation of PeNCs with metal oxide glasses, underscoring their significance in developing next-generation optoelectronic devices.

Exploring CsPbx3 (X = Cl, Br, I) Perovskite Nanocrystals in Amorphous Oxide Glasses: Innovations in Fabrication and Applications

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.
