Paper Abstract

Steady-state and time-resolved laser-fluorescence microscopy has been used to study the fluorescence emission from dye molecules embedded in micrometer-sized spherical polymer particles. Sharp ripple structures are observed in the fluorescence emission spectra of dyes. These structures are found to be consistent with the theoretical calculations of morphology dependent resonances (MDR's). Observed intensities of these MDR's in the fluorescence emission spectra are found to show excitation energy dependence. The MDR's in the beads do not appear to affect the radiative lifetime of the dyes.
