Quantum Dots Synthesis And Properties

Optical absorption and fluorescence line shapes of molecular aggregates are calculated using a variational method and the dynamical coherent potential approximation (DCPA) which account for strong exciton–phonon coupling. The formation and the quantum size effects of excitonic polarons are studied.
