Controlling the spatial distribution of quantum dots in nanofiber for light-harvesting devices

摘要

Confining quantum dots (QDs) into one-dimensional polymer nanostructures, we develop an inter-dot spacing control technique by which we can effectively isolate QDs in the solid-state film. The resultant isolated QDs in this nanostructure have clear monomeric features caused by attenuation of several problematic interactions, such as self-quenching. By incorporating isolated QD as an auxiliary light harvester, we can improve the performance of light-harvesting devices due to its additional absorption and efficient energy transfer. This study provides a general strategy that could be potentially useful for the spatial control of other functional moieties in various devices.
