摘要：
An inorganic oxide of the present invention has a composition represented by General formula (1): M 2 LnX 2 (AlO 4 ) 3 (where M includes Ca, Ln includes Tb, and X includes at least either one of Zr and Hf). Then, a number of Tb atoms in General formula (1) is 0.1 or more to 1 or less. Moreover, a crystal structure of the inorganic oxide is a garnet structure. A phosphor made of this inorganic oxide is capable of being excited by short-wavelength visible light, and can radiate narrow-band green light.
