Electron-phonon interaction in colloidal CdSe quantum dots embedded in different solid matrices

Colloidal semiconductor nanocrystals (quantum dots, QD) manifest specific temperature dependent luminescence. Here we analyse temperature dependences of CdSe QD luminescence spectrum shift for different composites: polymers, glasses, crystals. The analysis was performed in the terms of electron-phon...

Summary:Colloidal semiconductor nanocrystals (quantum dots, QD) manifest specific temperature dependent luminescence. Here we analyse temperature dependences of CdSe QD luminescence spectrum shift for different composites: polymers, glasses, crystals. The analysis was performed in the terms of electron-phonon coupling, that allows to find and compare the parameters of this interaction. The matrix influence on the T-dependence is also discussed.
