Since the discovery, this material and the related materials have been expected as a red phosphor for various applications; field emission display , electroluminescence device , long-lasting phosphor , and white photodiode . Control of morphology and size of phosphor particles is important for applications because these properties have a great influence on the luminescence intensity. The morphology and size of phosphor particles are often controlled by addition of a few percent flux to the starting materials of the phosphor.
