This Small Business Innovation Research (SBIR) Phase II project addresses the development of a new class of materials, namely polymeric nanomaterials with a very high refractive index, which will closely match the refractive index of inorganic semiconductors. The encapsulant materials consist of titania-nanoparticle-loaded silicone and epoxy. Titania (TiO2) has a refractive index of 2.68 and the admixture of TiO2 with a polymer would result in an increase of the refractive index. The well-known problem of excessive optical scattering will be overcome by proper use of surfactants and an encapsulation structure that employs thin films, with a thickness that is less than the average distance between scattering events. If successful the development of a new high-index encapsulant will have a tremendous impact on SSL technology because virtually all SSL devices made of inorganic semiconductors are packaged and encapsulated. A successful completion of the program will result in a worldwide paradigmatic shift in the packaging and encapsulation of optoelectronic devices. The broad deployment of efficient LED technology for general lighting applications would also result in electrical energy savings in the TWh range per year within the United States alone.

这个小型企业创新研究(SBIR)第二阶段项目致力于开发一种新型材料，即具有非常高折射率的聚合物纳米材料，这种材料将与无机半导体的折射率非常接近。包覆材料由纳米二氧化钛、有机硅和环氧树脂组成。二氧化钛的折射率为2.68，二氧化钛与聚合物的混合会导致折射率的增加。通过适当使用表面活性剂和使用厚度小于散射事件之间平均距离的薄膜的封装结构，可以克服众所周知的过度光学散射的问题。如果成功，新型高指数密封剂的开发将对SSL技术产生巨大影响，因为几乎所有由无机半导体制成的SSL器件都是封装和封装的。该计划的成功完成将导致全球范围内光电子器件封装和封装的典范转变。将高效的LED技术广泛应用于一般照明应用，仅在美国每年就可节省太瓦时范围内的电能。
