We have investigated exciton -phonon coupling and a zero-phonon exciton absorption line shape for lens-shaped quantum dots (QDs). Such dots occur in quasi-monolayer semiconductor heterostructures due to the interfacial roughness making quasi-2D excitons localize in lens-shaped quantum dot-like islan
