Abstract

Energy transfer from excited state donor to ground state acceptor dyes in polymer microparticles with a diameter of 30-60 μm was observed under lasing condition. The energy transfer efficiency was found to be higher with the increasing size of the particle. This result indicates that the excitation energy transfer efficiency can be controlled by the particle size without varying temperature and dye concentration. The dynamics of energy transfer was observed through picosecond time-resolved emission spectral measurements.
