Abstract
The CsPbX3 (X = Cl, Br, or I) perovskite quantum dots (PQDs) have become attractive luminescent materials in the field of optoelectronics due to their special optical properties, such as high quantum yield and color purity. However, the stability of PQDs hindered their practical applications. Here, the stability problems and degradation mechanism of PQDs were introduced in detail. Furthermore, several methods to enhance the intrinsic and extrinsic stability of PQDs would be mentioned. Among these strategies, the glass matrix encapsulation could provide the best protection for the PQDs inside. Here, various fabrication methods of CsPbX3 PQDs embedded with glass (PQDs@glass) were discussed. Furthermore, the difference between various kinds of glass matrix and the effect of the microstructural modulation of glass structure on the optical properties and stability of PQDs have been discussed completely. Ultimately, the potential applications of PQDs@glass in white light-emitting diodes and backlight liquid crystal displays have been discussed in detail. The comprehensive discussion in PQDs@glass may assist researchers in enhancing the stability of PQDs@glass and applying them to optoelectronic devices.
期刊介绍:
Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications.
The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms.
Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC).
Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
