White-Light-Emitting Nanocomposites for Custom-Designed Lighting Fixtures

Metalumen Manufacturing Inc.是一家为商业、医疗、教育和交通行业设计、工程、制造和供应各种照明产品的公司。开发具有定制指定光谱特性的新型照明设备，包括光谱功率分布、色温和显色指数，可以使公司在全球市场上获得显着的竞争优势。改善照明参数的可调性不仅将允许metumen目前所处的细分市场的增长，而且还将进入其他市场并创造新的机会。然而，由于难以获得所需比例的多色发射，可调谐白光发光荧光粉的构造仍然具有挑战性和昂贵。这项提案的目的是启动Metalumen和我在滑铁卢大学的团队之间的一个联合项目，以开发基于金属氧化物和碳纳米颗粒的新型可调、高效、环保的白光发光荧光粉。具有合适发射特性的纳米颗粒随后将被选定的有机或无机二次荧光团功能化，以产生具有所需光谱特性的白光发射。在项目的第二阶段，我们将探索将这些新的复合单一白光荧光粉整合到商业发光二极管中的方法，这些发光二极管是Metalumen产品的一部分。该项目将启动一个新的产品线，并为**Metalumen吸引新客户，最终将在加拿大市场创造新的就业机会。此外，不含稀土和有毒元素的新型节能照明光源的开发促进了加拿大社会的整体可持续性。

Metalumen Manufacturing Inc. is designing, engineering, manufacturing, and supplying various lighting**products for commercial, health care, educational, and transportation sectors. The development of new lighting**devices with custom specified spectral characteristics, including spectral power distribution, colour**temperature, and colour rendering index, could enable the company to gain significant competitive advantage**in the global market. Improvement in the tunability of the lighting parameters will not only allow for growing**the market segments Metalumen is currently in, but also entering other markets and creating new opportunities.**However, the construction of tunable white-light-emitting phosphors remains challenging and costly because of**the difficulties in obtaining multi-colour emission in the desired proportion. The purpose of this proposal is to**launch a joint project between Metalumen and my group at the University of Waterloo to develop new tunable,**efficient, and environmentally benign white-light-emitting phosphors based on metal oxide and carbon**nanoparticles. The nanoparticles with suitable emission properties will subsequently be functionalized with**selected organic or inorganic secondary fluorophores to generate white light emission with desired spectral**characteristics. In the second stage of the project we will explore the ways to incorporate these new composite**single white-light-emitting phosphors into commercial light emitting diodes that are a part of the Metalumen's**products. This project will enable the initiation of a new line of products and attraction of new customers to**Metalumen, which will ultimately result in the creation of new jobs on the Canadian market. Furthermore, the**development of new energy-efficient lighting sources free of rare-earth and toxic elements promotes the overall**sustainability in the Canadian society.
