Understanding the factors that influence the fabrication of plasmonic nanoassemblies and quantum dots (2026)
Abstract
Plasmonic nanoparticles and quantum dots have interesting optical properties useful for sensing applications. These optical properties can be tuned and enhanced by assembly of these nanoparticles into controlled morphologies, where factors such as the size, composition of the nanoparticles and precise arrangement are critical. This project has two aims: 1. Understand the morphology of a rational series of heterogeneous nanoassemblies of gold nanoparicles and quantum dots and relate to optical properties using static SAXS. 2. Assess real time structural evolution to monitor nucleation/growth of AuNPs on SiO2 cores via a seed-mediated method to gain insights not achievable with lab-based SAXS.
