| Research Abstract |
The method to stabilize dye-aggregates in aqueous media was developed. The aggregates enhanced the efficiency of the 2-photon excited fluorescence by up to 100 times compared to the solubilized dyes. The method to form a gold-shell on particle was also developed. Due to the enhancement of the excitation intensity induced by the shell, the aggregates adsorbed on the shell exhibited 3 times higher efficiency than those on the particle without the shell. Thus, the combination of dye-aggregation and the gold shell achieved several 100-fold higher efficiency compared to the solubilized dyes.
