Abstract

Abstract : Wavelength-tunable random lasers are achieved by thermally manipulating the intramolecular charge transfer process of gain molecules in metal–organic framework particles. Abstract : We propose a strategy to construct dynamically tunable random lasers by continuously adjusting the excited state of gain molecules spatially confined in the nanoporous channels of metal–organic framework particles. Wavelength-tunable random lasers are achieved by thermally manipulating the intramolecular charge transfer process of gain molecules. The wavelength-tunable response to thermal stimuli exhibits excellent reversible behavior. We envisage that such random lasers based on metal–organic frameworks will raise new fundamental issues regarding light–matter interactions in complex photonic media and open up a new avenue toward highly efficient light-emitting devices.
