Abstract

The forster resonance energy transfer (FRET) between different CdTe QDs and RhB were investigated by steady-state and femtosecond time-resolved photoluminescence spectra technique. Through the measurements on three different CdTe sample solutions, it was found that the FRET efficiency is proportional to the spectral overlap degree of CdTe QDs' emission and RhB's absorption. And the FRET efficiency was found to increase with the increase of the RhB's concentration, while the concentration increase to more than 4.5ž10-5 mol/L, the transfer efficiency decreases. The FRET efficiency can reach to 32.6% when RhB concentration is 4.5ž10-5 mol/L. With the wide use of FRET in biomolecular interaction analysis and cell physiology, the CdTe QDs-RhB hybrid systems could be a promising candidate for fluorescent probe and photodynamic therapy
