Room temperature excitons in hybrid organic-inorganic multiple quantum wells for strong coupling experiments

We report here the novel optical properties of naturally self-assembled hybrid organic-inorganic multiple quantum wells (OI-MQWs). These hybrids consist of a stack of alternative organic and inorganic nanolayers of widths ~ 6 and 10Aring respectively. They exhibit strong room temperature narrow exciton absorption and photoluminescence features due to quantum and dielectric confinements. The exciton peak position in these OI-MQWs could be tuned in the visible region by structural rearrangement. We have also demonstrated the capability of these heterostructures as strong candidate for exciton-photon strong coupling when sandwiched in metallic cavities.
