Abstract

The triangular pyramid nanostructure (TPN) raises a perfect prerequisite for the aggregation of surface plasmon resonances (SPRs). However, the application of TPN in thermoplasmonics has not yet been developed. The aim of this study is to explore the development potential of TPNs for enhanced noble metal photothermal applications. We investigated the optical absorption properties, photothermal conversion efficiency, and photothermal response under continuous wave irradiation of TPNs based on Ag and Au nanomaterials. The results show that TPN helps to enhance the SPR excitation of Ag and Au in the near-infrared. TPN based on noble metal nanomaterials shows good light absorption capacity and photothermal response. The photothermal conversion efficiencies of the TPN nanoparticle suspensions increased by 56.95% (Ag) and 49.57% (Au), respectively, compared to the same volume of noble metal nanospheres. This work is intended to researchers better understand the development potential of TPN in thermoplasmonics applications.
