Controlling Nanorod Alignment: From Single Particles to Large-Scale Assemblies

Abstract

Nanoparticles are versatile components of excitonic devices that can be made in an amazing diversity of shapes, sizes, materials and functionalisation.

Achieving their full potential, however, often requires control over their relative positions and orientations.

For example, nanorods have anisotropic optoelectronic properties that can be exploited to study the fundamental behaviour of excitons or utilised in devices for capturing or generating light.

In this talk, I'll explain how diverse driving forces, from particle-particle interactions to external fields, can be used to control the assembly of nanorods for different applications.

This will include discussion of recent and ongoing collaborations across the Centre.
