Abstract

CsPbBr3 quantum dots (QDs) have been widely applied in lighting, detection, display, and many other fields. However, due to their ionic crystal nature, further improvement in stability is still required for practical applications. To address this issue, this study employed a ligand engineering strategy to synthesize tributylphosphine (TBP)-modified CsPbBr3 QDs in a Zn2+-containing reaction system. Experimental results demonstrate that the modified QDs exhibit superior optical properties, as well as significantly enhanced thermal stability and resistance to UV photodegradation. The introduction of Zn2+ into the reaction system leads to a more uniform size distribution, improved monodispersity, and enhanced crystallinity of CsPbBr3 QDs. More importantly, the photostability of CsPbBr3 QDs under varied temperatures, cyclic heating–cooling processes, and prolonged UV irradiation is notably improved after Zn2+ incorporation. Furthermore, the TBP-modified CsPbBr3 QDs synthesized with Zn2+ assistance exhibit further enhanced photostability under all the aforementioned aging conditions. Additionally, we introduce a data-sonification method that translates the temporal evolution of photoluminescence spectra into audible audio signals using an oboe timbre, enabling auditory visualization of the aging process. This work not only provides an effective strategy for stabilizing perovskite QDs but also opens new possibilities for the application of luminescent materials in interactive displays.
