New material transforms light, creating new possibilities for sensors

Phys.org  June 12, 2023 Hybrid structures formed between organic molecules and inorganic quantum dots can accomplish unique photophysical transformations by taking advantage of their disparate properties. However ,the electronic coupling is typically weak, leading photoexcited charge carriers to spatially localize to the dot or to a molecule at its surface. A team of researchers in the US (University of Utah, University of Colorado, UC Riverside, UT Austin) has shown that by converting a chemical linker that covalently binds anthracene molecules to silicon quantum dots from a carbon–carbon single bond to a double bond, they accessed a strong coupling regime where […]
