Photoluminescence Study on Resonant Energy Transfer ProcessBetween Two Sizes of CdTe QDs Embedded in Gelatin Films

Abstract
Thioglycolic-acid-stabilized CdTe nanocrystals (NCs) are synthesized with wet chemistry method.Energy transfer process between two sizes of CdTe nanoceystals embedded in gelatin films is investigated.Photoluminescence results for the mixed system show that long-range resonance energy transfer (LRRT) between QDs occurs when nanocrystals are in close proximity.From PL results,quenching efficiency-distance curve can be obtained.This critical distance R0=9.5nm from our mixed system agree well with other’s results obtained in solid films. -
