We present a simple and versatile mechanism for the reversible photoswitching of dye-doped core–shell nanoparticles. Photochromic dithienylethenes are incorporated into the outer shell, close enough to the dyes entrapped in the core to efficiently quench them by energy transfer when photoconverted with UV light. The emission can be switched back on by irradiation with lamda 4 450 nm.

Abstract

We present a simple and versatile mechanism for the reversible photoswitching of dye-doped core–shell nanoparticles. Photochromic dithienylethenes are incorporated into the outer shell, close enough to the dyes entrapped in the core to efficiently quench them by energy transfer when photoconverted with UV light. The emission can be switched back on by irradiation with lamda 4 450 nm.
