Development of energy down-conversion device using photo-assisted self assembly

为了实现高效的能量下转换器件，首先，我提出了一种利用修饰性光子辅助工艺进行尺寸控制的新方法。实现了氧化锌量子点(QD)尺寸分布的急剧减小。其次，我利用修饰性的光子辅助过程开发了纳米粒子对形成(液滴)的自组装。利用氧化锌量子点和染料纳米粒子，选择入射光波长，实现了氧化锌和染料纳米粒子液滴对的合成，证实了紫外光到可见光的高效能量下转换。

To realize high efficient energy down conversion device, first, I developed new size controlling method using dressed photon assisted process. And drastic decrease in the size distribution of ZnO quantum dot (QD) was realized. Second, I developed self assembly of nano particles pair formation (droplet) using dressed photon assisted process. By using ZnO QD and dye nanoparticles and selecting incident light wavelength, I realized to synthesize the droplet of ZnO and dye nanoparticles pair, and confirmed high efficient energy down conversion from ultra violet light to visible light.
