摘要:
The present invention provides a new phosphor with a controllable emission wavelength without using a number of rare and expensive raw materials in forming the composition. The phosphor includes a compound including a fluorescent ion and having a garnet structure including a rare earth element, aluminum, and oxygen. The compound has such a composition that a combination of the rare earth element and the aluminum of the compound is partially replaced with a combination of alkaline earth metal and zirconium (Zr) or alkaline earth metal and hafnium (Hf).
