Molecular versus exciton diffusion in fluorescence-based explosive vapour sensors

Molecular versus exciton diffusion in fluorescence-based explosive vapour sensors

The diffusion of p-nitrotoluene vapours into polymer or dendrimer sensing films follows Super Case II dynamics in which the quenching efficiency is strongly correlated to an accelerating analyte front propagating through the neat film rather than being reliant on exciton diffusion.
