英文摘要: In the present proposal, the applicant and co-workers will construct (noble metal-semiconductor) hybrid nanostructures based on self-assembly technique, and systematacially study the various effects (including composition, size, shape of building blocks and distance and medium between the building blocks) of building blocking on the interaction of SPR and exciton, explore the relationship of structures of (noble metal-semiconductor) hybrid and photo-physical properties, modulate the electron transfer and energy transfer behaviors of the hybrid based on the construction design. Then, the applicant hope to rationally design some (noble metal-semiconductor) hybrid nanostructures for fluorescent sensing and photocatalysis applications.
