The purpose of the present invention is to provide a fine fluorescent particle which suffers no concentration quenching and has low ecotoxicity. Specifically, the present invention relates to a fine fluorescent particle comprising a network polymer and containing an AIE-active compound, characterized in that the AIE-active compound is, for example, a compound represented by general formula (1).n(In formula (1), E is a silicon or germanium atom, R 1 and R 2 are the same or different and are each a C 1-6 hydrocarbon group or an(un)substituted phenyl group, and R 3 , R 4 , R 5 , and R 6 are the same or different and are each an (un)substituted phenyl group.) |
