Abstract

Highly luminescent silica-coated CsPbX₃ quantum dots (QDs) with good photostability were synthesized and coupled with photochromic diarylethene to modulate the QDs’ photoluminescence (PL). Upon successive UV and visible light irradiation, the PL emission from the silica-coated CsPbX₃ QDs was repeatedly quenched and restored, demonstrating the promising feasibility of the QD/diarylethene-based photoswitches.
