Abstract: Micelle organizes the donor and acceptor molecules into a discrete volume region, facilitates the energy transfer and enhances the intensity of sensitized RTP.This paper reports the sensitized RTPof biacetyl by naphthalene in SDSmicellar solution, and indicates that the intensity of sensitized RTPwas correlative with the Poisson distribution and determined by values of PDless×PAless which is the probability of less donor and less acceptor occurred in the same micelle.The linear range of detection is 0-8.0×10-5mol/L.Typically, the limit of detection for naphthalene in SDSis 6.5×10-8mol/L.
