Luminescent nanoparticle and luminescent labeling material for pathological diagnosis use

Abstract

A luminescent nanoparticle contains a first luminescent compound and a second luminescent compound. The first luminescent compound is excited by light irradiation and has a function of transferring energy due to the excitation to the second luminescent compound. The second luminescent compound has a function of receiving the energy due to the excitation to emit light. A content of the first luminescent compound to a total amount of the luminescent nanoparticle is in the range of 4 to 90% by mass.
