Abstract
Semiconductor nanoparticles of the present invention are particles each having a core-shell structure that includes a core and a shell surrounding the core. The core includes (AgIn)ZnS(0.4≦x≦0.95 holds). The shell includes ZnS or ZnO, and the semiconductor nanoparticles each have at least one hydrophilic functional group on a surface of the shell. As the hydrophilic functional group, for example, a carboxyl group or a sulfo group may be mentioned. Since having a low toxicity and a high emission quantum yield, the semiconductor nanoparticles as described above may be used for a fluorescent probe for biological labeling.
