Improving the thermal resistance of fluorescent CsPb(Br,I) perovskite quantum dots by surface modification with perfluorodecanoic acid.

CsPb(Br,I) quantum dots (QDs) show application potential for optoelectronic devices. However, their thermal degradation is a significant problem. In this work, the effects of perfluorodecanoic acid (PFDA) modification on the photoluminescence (PL) and thermal resistance of CsPb(Br,I) QDs were evaluated.
