Vibronic Excitons in Anthracene as Investigated by Thermoreflectance Spectra
スポンサーリンク
概要
- 論文の詳細を見る
Thermoreflectance spectra are measured for the vibronic bands of the lowestsinglet exciton in anthracene at 10 K. Spectral features due to the 0 -0 excitons,vibrons and the multi-particle band edges are interpreted in terms of a classicaloscillator model. The characteristic profile of the 1:wo-particle absorption bandassociated with the 390 cm ' intramolecular vibration is compared with a modelcalculation by the dynamical coherent potential approxima.tion model. It isconcluded that the density of states curve for the ext:iton has a strong one-dimen-sional character near the lower band edge, but at ltigher energies it is of three-dimensional character having a large density of states near the upper edge.
