Abstract
The photoluminescence (PL) properties of the guest–host films, using CdTeS/ZnS core shell quantum dots (QDs) as the guest and organic small-molecule material Alq3 as the host, are studied by steady-state and time-resolved PL spectroscopy. Both the relative intensity and the PL lifetime are intensively dependent on the weight ratio of Alq3 and CdTeS/ZnS QDs. The detailed analysis provides clear evidence for a Förster energy transfer from Alq3 host to QDs guest, based on the nonradiative resonant transfer mechanism. The results are relevant to the application of hybrid organic/inorganic systems to OLEDs.
