STTR Phase I: Novel Materials & Coatings for Efficient White Down-Converting Light Emitting Diodes

这个小型企业技术转让(STTR)第一阶段项目包括开发用于紫外光发光二极管的光致发光荧光粉和涂层材料，使白光发光二极管具有远远超过当前技术水平的高颜色纯度、效率和寿命。通过使用几种光致发光荧光粉的有效混合物来下转换发光二极管发出的紫外线幅度发射，将产生白光发光二极管光。这些材料将使用一种新开发的选择性沉积工艺(电泳)与发光二极管芯片光学耦合，该工艺目前正由磷化技术公司和安捷伦技术公司联合申请专利。改进的固态和荧光粉材料技术预计将在未来几年给照明行业带来巨大变化。这种新的白色光源将改变我们的生活方式，以及我们消耗能源的方式。全球照明用电量将减少50%以上，全球总用电量将减少10%以上。全球节省的电力将超过1000太瓦时/年，价值约为1000亿美元/年，以及在发电过程中产生的约2亿吨碳排放。此外，超过125千兆瓦的发电能力将被腾出用于其他用途或不需要创造，节省超过500亿美元的建设成本。最后，对环境的影响将是巨大的，从而消除汞污染的主要来源之一。

This Small Business Technology Transfer (STTR) Phase I project involves the development of photoluminescent phosphors and coating materials for ultraviolet light emitting diodes that will make possible a white light emitting diode having high color purity, efficiency and lifetime far exceeding those of current state of the art. The white light emitting diode light will be produced by down-converting the ultraviolet amplitude emission from light emitting diodes using an efficient mixture of several photo-luminescent phosphors. The materials will be optically coupled to light emitting diode dies using a newly developed selective deposition process (electrophoretic) that is currently being patented jointly by PhosphorTech and Agilent Technologies. Improved solid state & phosphor material technologies are expected to result in dramatic changes in the lighting industry over the next several years. This new white light source would change the way we live, and the way we consume energy. The worldwide amount of electricity consumed by lighting would decrease by more than 50%, and total worldwide consumption of electricity would decrease by more than 10%. The global savings would be more than 1,000TWh/yr of electricity at a value of about US$100B/year, along with the approximately 200 million tons of carbon emissions created during the generation of that electricity. Moreover, more than 125GW of electrical generating capacity would be freed for other uses or would not need to be created, a savings of over US$50B of construction cost. Finally, the impact on the environment will be dramatic, resulting in the elimination of one of the main sources of mercury pollution
