Abstract

Garnet silicate is garnet silicate containing, as a main component, silicate represented by a general formula: LuCaMg(SiO). The garnet silicate includes primary particles having a particle shape derived from a crystal structure of garnet. Moreover, the garnet silicate further contains alkaline metal including at least lithium, in which a content of the alkaline metal is less than 2000 ppm. The garnet silicate phosphor includes garnet silicate and ions which are included in the garnet silicate and function as a light emission center. The wavelength converter includes the garnet silicate phosphor. A light emitting device includes the garnet silicate phosphor or the wavelength converter.
