Coherent Random Lasing Realized in Polymer Vesicles

open access: yesPhotonic Sensors, 2019
We have demonstrated the realization of a coherent vesicle random lasing (VRL) from the dye doped azobenzene polymer vesicles self-assembled in the tetrahydrofuran-water system, which contains a double-walled structure: a hydrophilic and hydrophobic part.
