| Description | Fabrication techniques for Si NC formation in oxide nitride materials system to optimize the luminescent properties of the NC we were able to improve the incorporation of erbium into silicon oxide with applications to telecomms market. The use of Bismuth as a light emitter was shown to be ineffective due to out diffusion. The use of rapid thermal processing was shown to control the size of silicon nanocrystals and tune their emission wavelength |
| Exploitation Route | Solid characterization data of influence of process conditions on the luminescent properties of NC films synthesized by ion implantation. could be of use in the photovoltaic field, the process developed has been used by the US renewable energy laboratory for improved energy harvesting in Silicon based solar cells |
