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.

涂料具有许多不同的功能，并可应用于各种领域。在这项研究中，我们建议开发金属纳米颗粒涂层应用于宝石表面，以提高其视觉吸引力。这是通过激发由入射光与纳米颗粒涂层产生的金属-电介质界面相互作用产生的表面等离子体激元来实现的，从而增强背散射。这项研究的目的是使用等离子体工艺来产生纳米颗粒并将其涂覆在宝石上。将进行各种光学技术和机械测试，以验证涂层的性能和行为。计算研究补充了实证调查。虽然研究的重点与我们的工业合作伙伴的核心活动相一致，但拟议项目的科学和技术基础可能适用于广泛的与加拿大工业相关的企业（例如，航空航天、远程通信、计算机处理），可能改善生活质量和一般健康，对环境的有益影响以及增加的经济回报。
