| titleOfInvention | Fluorescent substance, method for production thereof, and wavelength converter, light-emitting device and lighting device |
| abstract | There are provided a phosphor capable of emitting yellow to green color with high quantum efficiency, a method for production thereof, and a wavelength converter, an illumination device and a luminaire each capable of having improved luminous efficiency. The phosphor contains M 1 , Eu and Si, wherein M 1 represents at least one selected from Sr, Ba and Ca. The phosphor comprises a crystal represented by (M 1 ,Eu) 2 SiO 4 as a main crystal and has a divalent Eu ion concentration of 90% or more, as determined from an X-ray absorption near edge structure (XANES) spectrum, based on the total amount of divalent and trivalent Eu ions. The phosphor also has a (M 1 +Eu)/Si molar ratio of less than 2, wherein the (M 1 +Eu)/Si molar ratio is the sum of the molar ratio of M 1 to Si and the molar ratio of Eu to Si. |
