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

Metalen制造公司为商业、医疗、教育和交通部门设计、工程、制造和供应各种照明产品。开发具有定制光谱特性(包括光谱功率分布、颜色**温度和显色指数)的新照明**设备，可以使该公司在全球市场获得显著的竞争优势**。照明参数可调整性的改进不仅可以扩大Metalen目前所处的细分市场，还可以进入其他市场并创造新的机会。**然而，可调白光荧光粉的建造仍然具有挑战性和成本，因为**在获得所需比例的多色发射方面存在困难。这项提议的目的是**启动Metalen和我在滑铁卢大学的团队的一个联合项目，开发基于金属氧化物和碳纳米颗粒的新型可调、高效和环保的白色发光材料**。具有合适发射性能的纳米粒子随后将与**选定的有机或无机二次荧光团一起功能化，以产生具有所需光谱**特性的白光发射。在该项目的第二阶段，我们将探索将这些新的复合**单个白色发光荧光粉集成到Metalen**产品的商用发光二极管中的方法。该项目将启动一系列新产品并吸引新客户到**Metalen，这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.
