Abstract: K1.00266 : Experimentally determined optical-properties of monodisperse graphene quantum dots with controlled size and geometry
Author:
In this talk, we will present a novel route for high throughput
production
of monodisperse GQDs with controlled spatial dimensions (5 nm -
100 nm at 1
nm resolution) and geometry (squares, rectangles, and triangles).
We would
show the first detailed experimental demonstration of the GQD
optoelectronic-property-tuning via tailoring of their spatial
dimensions and
geometry. Further, we would be presenting the detailed
structural, optical
and electronic characterization of the as-obtained GQDs via various
microscopic and spectroscopic techniques. While the top down
methods of
fabrication including lithography-based methods or sonochemical
methods are
either extremely low throughput or have limited control on GQDs'
dimensions
and geometry; the bottom-up fabrication methods are limited by the
achievable size ($<$ 3 nm).
