Energy transfer and the photon lifetime within an aerosol particle.
نویسندگان
چکیده
The theory of enhanced energy transfer within an aerosol particle based on donor coupling to morphological dependent resonances is tested for the first time to our knowledge. The correspondence between theory and experiment is good and allows one to obtain the photon lifetime within the longest-lived resonances. A comparison between this lifetime and the lifetime as obtained by Mie theory is discussed.

Imaging enhanced energy transfer in a levitated aerosol particle
Energy transfer experiments are carried out at dilute concentrations of donors ~10 M , coumarine 334! and acceptors ~5310 M , sulforhodamine 101! in a levitated microdroplet ~diameter, 2a519 mm!, using an aerosol particle fluorescence microscope. Microphotographs in donor and acceptor luminescence show that the transfer mechanism is not of a Förster type, but is mediated by morphology dependent...
