A detailed study of the Localized Surface Plasmon Resonances (LSPR) of a range of solution phase silver nanostructure sols and their refractive index sensitivity is presented. This work focuses on developing a thorough ...

Near-infrared optical gain in luminescent polymeric slab asymmetric waveguides has been investigated by use of amplified spontaneous emission. Upon nanosecond photopumping, the waveguides have shown a small-signal gain ...

Carbon-based nanostructures have been at the forefront of scientific research for the last couple of decades due to their unique properties, giving rise to many potential applications especially for electronics. Their ...

Equal-sized bubbles of average diameter less than one millimetre are found to spontaneously crystallise upon formation. While previously employed by Sir Laurence Bragg as an ideal system with which to study crystalline ...

This work describes the application of a novel multi-parameter scanning probe technique to the study of a model semiconductor and a metal oxide surface. Our novel scanning probe technique enables the simultaneous measurement ...

The objective of the work performed in this thesis is to prepare Polymer Dispersed Liquid Crystal (PDLC) systems under optimised preparation conditions and with improved liquid crystal/polymer composition for thermo-and ...

Transparent conducting oxide (TCO) materials, formerly regarded as degenerate conductors of only one carrier type, can now be considered as transparent semiconductors possessing the potential for integration into more ...

Tuneable Diode Laser Absorption Spectroscopy (TDLAS) technology for gas sensing has had reliance on, and has benefited from, devices developed for the optical communications sector, namely distributed feedback laser diodes. ...

Widely tunable semiconductor lasers will play a critical part in future technologies. Tunable lasers are rapidly replacing fixed wavelength lasers in dense wavelength division multiplexing (DWDM) optical communications. ...
