Abstract
Au nanopyramid particles (Au NBPs) are highly desirable for its
remarkable optical properties such as long-range tunable resonance. It
has wide applications in room-temperature bioimaging probes and
bioanalytical sensors. In this paper, we synthesize Au NBPs with a
purity of 95%, and obtain the optical response of Au NBP in near
infrared regime. We find that Au NBPs have small mode volume of electric
field which can lead to the strong coupling with quantum dots at room
temperature. It provides novel applications for Au NBPs in fields of
materials, biomedical science, and quantum information
