Long-range resonance transfer of electronic excitations in close-packed CdSe quantum-dot solids

Abstract
We show spectroscopically that electronic energy transfer in close-packed CdSe quantum-dot (QD) solids arises from dipole-dipole interdot interactions between proximal dots. We use cw and time-resolved photoluminescence to study electronic energy transfer in optically thin and clear, close-packed QD solids prepared from CdSe QD samples tunable from 17 to 150 Å in diameter (σ1996 The American Physical Society.
