摘要

随机分布的二氧化硅纳米线在整个可见光波段都具有很高的反射率,可以作为高效光电封装的白光涂层。本文提出了一种改进的工艺,将二氧化硅纳米线作为LED反射杯的光学涂层重新组合,形成LED封装中的扩散反射表面。这种复合是通过两步工艺实现的:首先通过巧妙的磁搅拌将合成的二氧化硅纳米线分散在蒸馏水中,然后通过范德华力将其吸收在镜面上。这项工作为改善照明系统提供了一种替代的低成本方法。

Silica nanowires as new coating material for high-efficiency light reflection in LED system
Randomly distributed silica nanowires show highly reflectivity in the whole visible wavelength, which can be used as white light coating for high-efficiency optoelectronic packaging as affirmed by our previous work. In this work, an improved process has been developed to recombine the silica nanowires as optical coating of LED reflector cup to form diffusive reflecting surface in LED packaging. This recombination was realized through two-step process: the synthesized silica nanowires were first dispersed in distilled water via artful magnetic stirring and then absorbed on specular surface by Van der Waals' force. This work provides an alternative and low-cost method for the improvement of lighting systems.
