Abstract
A manufacturing method for a nanocrystal light emission substance having a nano structure crystal, doped with an activator and cured with ultraviolet light. The nanocrystal light emission substance is synthesized by a liquid phase co-precipitation process. During the liquid phase reaction, an organic acid, such as acrylic acid or methacrylic acid, is added. Alternatively, a high molecular organic acid, such as polyacrylic or polymethacrylic acid, polystyrene, is added after the liquid phase reaction. The resulting substance is then cured with ultraviolet light.
