Abstract

This paper investigates how structural features of noble metal nanoparticles affect their photothermal properties. Using PEEL, we fabricated a range of Au nanopyramid-like particles with surface plasmon resonances tunable from visible to near-infrared wavelengths. By systematically varying geometric parameters including size, shell thickness, and presence or absence of tips, we determined which factors were most important in heat generation. For solutions with the same Au content, we discovered that pyramidal particles with thin shells and having sharp tips showed the largest photothermal response.
