Exciton-enhanced infrared spectroscopy with organometallic perovskite nanoplatelets

Nanoplatelets of organometallic perovskites were found to efficiently improve molecular infrared absorption. There exist a specific quantum well structure and strong quantum confinement in the nanoplatelet. Both endow the platelet excitons with low bandgap energies. The excitons were excited by infr...

Description
Summary:Nanoplatelets of organometallic perovskites were found to efficiently improve molecular infrared absorption. There exist a specific quantum well structure and strong quantum confinement in the nanoplatelet. Both endow the platelet excitons with low bandgap energies. The excitons were excited by infrared photons and electromagnetically enhanced molecular infrared spectroscopy.
