OPTICAL WAVELENGTH CONVERSION MATERIAL, OPTICAL WAVELENGTH CONVERSION DEVICE, AND LIGHT EMITTING DEVICE
An optical wavelength conversion member according to one aspect of the present disclosure includes a ceramic sintered body, wherein the ceramic sintered body has a fluorescent phase containing, as a main. component, fluorescent crystal grains that generate fluorescence in response to incident light, and a translucent phase containing translucent crystal grains as a main component. The optical wavelength conversion member includes a metal layer having light reflectivity and provided on a side of the ceramic sintered body opposite the side on which the light is incident, and a dielectric multilayer film including dielectric layers having different optical refractive indices and provided between the ceramic sintered body and the metal layer.
