ABSTRACT:
There is provided a novel method for manufacturing a light-emitting material composed of II-VI group semiconductors having a nano structure crystal and which is optimally doped with an activator. In a manufacturing method for the light-emitting material, a II-VI group semiconductor doped with an activator by a liquid phase reaction having a co-precipitation product is formed and an organic acid is added to the liquid phase reaction system. In another manufacturing method for the light-emitting material, a II-VI group semiconductor doped with an activator by a liquid phase reaction having a product co-precipitation is formed and a high molecular organic acid or polystyrene is added after the end of the liquid phase reaction.
