报告摘要：
An important aim of contemporary nanophotonics is to manipulate light by using
nanometre length scale structures made of dielectric, metallic or hybrid materials.
Such plasmonic or photonic nanostructures, if produced over large area, can be widely
used for many real life photonic and optoelectronic applications, e.g. photovoltaics,
metamaterials, waveguiding, and biosensing. Unfortunately, up to now nanostructures
with precise geometry are mostly fabricated using electron beam or focused ion beam
lithography, which, nevertheless, are also characterized by high cost, complicated, and
slow manufacturing processes and limited sample area. In contrast, the technique of
natural self-assembly is an attractive route to creating large-area nanostructured arrays
efficiently and cheaply.
In this talk, I am going to demonstrate how the self-assembly technique based on
colloidal nanospheres can be used to fabricate hybrid colloidal plasmonic-photonic
crystals, followed by the introduction of the unique optical properties of such
nanostructures. Specifically, I will demonstrate the fluorescence reshaping effect in a
2-dimensional hybrid crystal, the interplay between surface and volume diffraction
resonances in a 3-dimensional hybrid crystal and the enhancement of light harvesting
efficiency by a hybrid heterocrystal.

报告人简介：
Dr. Boyang Ding received his Master degree from the Royal Institute of Technology (KTH, Sweden) in 2005 and his PhD degree from the University College Cork, Ireland in 2010. He then moved to
the Johannes Kepler University Linz, Austria working for the European Research Council project ‘Active Nanophotonics’. Since 2013 he is a Postdoctoral research fellow at the Physics Department,
University of Otago, New Zealand. Since his PhD study, he has been investigating the optical properties of metallic/dielectric nanostructures, based on the self-assembly techniques. He authored a number of pioneering results in the physics of periodic and irregular ensembles of nanostructures. His current research focus is the light absorption/emission on thin film architectures.
