Recent Advances in CsPbX3 (X = Cl, Br, I) Perovskite NCs@Glass: Structures, Characterizations, and Applications

Abstract

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.
