Rare earth aluminum garnet type phosphor and light emitting device using the same

Without the composition intensive scarce and expensive raw materials, to provide a novel phosphor capable of controlling emission wavelength. Wherein ions fluoresce a compound constituting the garnet structure containing a rare earth element and aluminum and oxygen, in terms of composition, the element combination of a rare earth element and aluminum constituting the compound, alkaline earth metal and zirconium ( Zr), or are partially substituted with any element combination of alkaline earth metals and hafnium (Hf).
