Abstract
Various display devices utilize colloidal quantum dots (QDs) for photoluminescent (PL) and electroluminescent (EL) applications owing to their exceptional optical properties, including sharp emission bandwidths, tunable emissions spectra, and photoluminescence quantum yields approaching unity. Since the commercialization of PL-based devices, researchers have shifted focus to the commercialization of EL-based devices and patterning processes. Over the past decade, the performance of EL devices has been dramatically enhanced through the meticulous optimization of the device architecture. In addition, solution-based QD patterning techniques have advanced, offering methods that minimize damage to the coated QDs while preserving their intrinsic properties effectively. Recent innovations include the development of ink formulations that improve the stability of QDs under ambient conditions and the use of photolithographic and soft lithographic techniques to achieve high-resolution patterning. This article reviews the recent advancements in various EL-based devices and solution-based methods for QD patterning, highlighting their potential to enable more complex, multi-color displays, and their implications for next-generation consumer electronics.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
