Description
Summary: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. Wavelength-tunable random lasers are achieved by thermally manipulating the intramolecular charge transfer process of gain molecules in metal-organic framework particles.
