A temperature-dependent emission is observed for CdTe nanoparticles connected to Au nanoparticles by a flexible poly(ethyleneglycol) (PEG) link acting as a molecular spring (see picture). The extension of the PEG springs varies depending on the temperature, which causes variations in CdTe emission caused by plasmon–exciton interactions. A theoretical model of plasmon–exciton coupling explains the optical and thermal effects.
