Near-infrared chromophores and fluorophores are useful for many types of imaging applications and could be useful for fiberoptic communications, but it is challenging to find such species with high emission quantum yields and controllable exciton dynamics. Several types of colloidal quantum dots have >50% quantum yields on the near infrared, but their long radiative lifetimes make them poor energy donors. In this talk, mechanisms for extraction of near-infrared excitons from quantum dots within assemblies with molecules are explored, and some applications, such as photocatalysis, are highlighted.
