Coatings serve a number of different functions and find application in a variety of fields. In this study, wepropose to develop metal nanoparticulate coatings to be applied to the surface of gemstones to enhance theirvisual appeal. This is to be achieved through the excitation of surface plasmons generated by incident lightinteracting with the metallo-dielectric interface resulting from the nanoparticle coating, leading to enhancedbackscattering. The research study aims to use a plasma process to generate the nanoparticles and subsequentlycoat the gemstone. A variety of optical techniques and mechanical tests will be performed to characterise theperformance and behaviour of the coatings. Computational studies complement the empirical investigations.While the focus of the research aligns with the core activities of out industrial partner, the potential exists thatthe scientific and technical fundamentals of the proposed project may be applied to a broad range ofindustrially-relevant ventures to Canada (for example, aerospace, telelcommunications, computationalprocessing) with possible improvements to quality of life and general health, beneficial impact on theenvironment as well as increased financial rewards.
