This Small Business Innovation Program (SBIR) Phase I project aims to further develop a novel and proprietary phosphor material system for use in phosphor-converted light-emitting diode (pcLED) applications that will improve pcLED energy efficiency up to 20%. In display backlighting, 20-40% of the light emitted by the state-of-the-art phosphors miss the sweet spot of the display?s color filters resulting in unused light and wasted energy. Similarly, in general lighting approximately 15% of the emitted light falls outside the visible spectrum, again resulting in wasted energy. The technology developed in this SBIR project is phosphor material utilizing a novel chemistry that exhibits a narrow light emission spectrum to increase LED brightness and energy efficiency by 10-20% in display backlighting and up to 15% in general lighting applications. Prototype materials have been synthesized that exhibit a narrow emission peak at target wavelengths, and the next steps include optimization and characterization of the most effective compositions. The anticipated results of this SBIR Phase I project are narrow-band phosphor materials that exhibit performance characteristics commensurate with industry standards.The broader impact/commercial potential of this project is the development of a novel phosphor material system that drives up to a 20% improvement in energy efficiency of phosphor-converted LEDs (pcLEDs) over current state-of-the-art phosphor material systems in nearly all pcLED applications. The market for LED phosphors in 2012 was roughly $500 million and is expected to reach $1.2 billion by 2016, of which $996 million will be addressable by narrow-band phosphors. The 20% improvement in the packaged LED efficiency will also trigger a cascade of tangible impacts at the end-product system level such as using fewer LEDs, increasing efficacy (lumens per watt) and mobile device battery life, reducing electronic driver complexity, reducing heat, a thinner form factor, and a far more brilliant color gamut.

该小型企业创新计划（SBIR）第一阶段项目旨在进一步开发一种新型专有磷光体材料系统，用于磷光体转换发光二极管（pcLED）应用，将pcLED能效提高20%。在显示器背光中，20-40%的光由最先进的荧光粉发射错过了显示器的最佳点？的彩色滤光片，导致未使用的光和浪费的能源。类似地，在一般照明中，大约15%的发射光福尔斯落在可见光谱之外，再次导致能量浪费。该SBIR项目开发的技术是利用一种新型化学物质的磷光体材料，该材料具有窄的发光光谱，可将LED亮度和能效提高10-20%，在显示器背光照明中可提高15%，在一般照明应用中可提高15%。已经合成了在目标波长处表现出窄发射峰的原型材料，接下来的步骤包括优化和表征最有效的组合物。该SBIR第一阶段项目的预期成果是窄带荧光粉材料，其性能特性符合行业标准。该项目的更广泛影响/商业潜力是开发一种新型荧光粉材料系统，在几乎所有的荧光粉转换LED（pcLED）应用中，该系统比当前最先进的荧光粉材料系统的能效提高高达20%。2012年LED荧光粉市场约为5亿美元，预计到2016年将达到12亿美元，其中9.96亿美元将由窄带荧光粉解决。封装LED效率提高20%还将在最终产品系统层面引发一系列切实的影响，例如使用更少的LED，提高效率（每瓦流明）和移动终端电池寿命，降低电子驱动器复杂性，减少热量，更薄的外形尺寸以及更明亮的色域。
