摘要
Reflection, transmission, and resonant Rayleigh scattering of a J-aggregate monolayer have been measured at the Brewster's angle of the substrate. Low-energy shift of the resonance Rayleigh scattering relative to the absorption peak corresponds to large variation of homogeneous width and observed energy dependence of homogeneous width can be attributed to the higher degree of localization of the low-energy excitons.
