Abstract

Semiconductor quantum dots have shown great potential in display applications due to their excellent optoelectronic properties, especially QLED displays with wide color gamut, high efficiency, flexibility, and smartness. However, the limited available efficient, narrow-luminescent, and environmentally friendly quantum dot systems remain a significant obstacle to quantum dots for display applications. Ag-In-S (AIS) quantum dots and derivatives are highly promising eco-friendly candidates due to their low toxicity and fully spectrally tunable band-edge emission. Here, we summarized the optoelectronic properties, synthesis strategies, narrow-emission strategies, and QLED optimization of AIS quantum dots and derivatives. Finally, we provide an outlook on future research of AIS quantum dots in QLED display technology, emphasizing the importance of further improving their color purity and device efficiency to drive breakthroughs in commercial applications.

AIS量子点及其衍生物在显示应用中的进展与挑战：从合成到qled

半导体量子点以其优异的光电性能，特别是具有宽色域、高效率、柔性和智能的QLED显示，在显示领域显示出巨大的应用潜力。然而，有限的高效、窄带发光和环境友好的量子点系统仍然是量子点显示应用的一个重大障碍。Ag-In-S （AIS）量子点及其衍生物由于其低毒性和全光谱可调谐的带边发射而成为极有前途的环保候选者。本文综述了AIS量子点及其衍生物的光电特性、合成策略、窄发射策略以及QLED优化。最后，我们对AIS量子点在QLED显示技术中的未来研究进行了展望，强调进一步提高其颜色纯度和器件效率对于推动商业应用突破的重要性。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
