Outline of Final Research Achievements

Light energy conversion systems using semiconductor nanoparticles have been attracted much attention. In this study, we synthesized multinary semiconductor nanoparticles of low toxicity with solution phase methods and investigated their activities for light energy conversion. The photocatalytic activity of the ZnS-AgInS2 solid solution (ZAIS) nanoparticles was remarkably varied, depending on their particle composition, size, and shape. In particular, dumbbell-shaped ZAIS particles, composed of two ellipsoidal nanocrystals deposited on a rod-shaped particle, showed higher photocatalytic activity than those of single-component counterparts, due to the efficient charge separation at Type II heterojunction inside a particle. Furthermore, thin film photoelectrodes, composed of in the ZnTe-AgIgTe2 solid solution (ZAITe) nanoparticles, exhibited higher activity for photocurrent generation when the heterojunction was formed by the deposition of In2S3 shell layer on the ZAITe film surface.
