M. Lankers et al., RAMAN AND FLUORESCENCE-SPECTRA OF SINGLE OPTICALLY TRAPPED MICRODROPLETS IN EMULSIONS, Applied spectroscopy, 48(9), 1994, pp. 1166-1168
By means of an optical trapping technique we have been able to trap si
ngle microdroplets in emulsions and to observe their Raman and/or fluo
rescence spectra. In the fluorescence spectra we could observe additio
nal morphology-dependent electromagnetic resonances, from which the ra
dius of the sphere can be determined.
