摘要：

Quantitative energy transfer from CdSe nanocrystals to a single. conjugated organic dye is observed in the system shown. The energy transfer can be modulated by altering the surface chemistry of the CdSe nanocrystal. The ability of one dye molecule to Capture the exciton energy from a semiconductor nanocrystal effectively enhances the absorption cross section of the dye.
