合成了具有良好光稳定性的高发光性二氧化硅包覆的CsPbX 3量子点，并将其与光致变色二芳基乙烯偶联以调制量子点的光致发光。在连续的紫外光和可见光照射下，从二氧化硅涂覆的CsPbX 3量子点的PL发射被反复淬灭和恢复，证明了量子点/二芳基乙烯基光开关的有前途的可行性。
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.
