To obtain nano-sized crystals of organic phosphor for high efficiency and narrow band emission, we proposed fine-hole structure and wettability pattern control. As a result, we found that we can control the crystal growth field by wettability control. We also succeeded in making nano-size organic phosphor crystals.
