Abstract:
1. A light-emitting device, comprising: a light-emitting element for emitting light of a predetermined wavelength; and a ceramic layer containing a phosphor, the phosphor being excited by light emitted from the light-emitting element and giving off fluorescent light of a wavelength different from an excitation wavelength, the ceramic layer containing the phosphor, a hardened product of an organometallic compound, a layered silicate mineral, and an inorganic particulate, the hardened product of the organometallic compound content of the ceramic layer being 2 to 50 wt %, the layered silicate mineral content of the ceramic layer being 0.5 to 20 wt %, the inorganic particulate content of the ceramic layer being 0.5 to 50 wt %, a mean particle diameter of a primary particle diameter of the inorganic particulate being 0. 001 to 20 μm, and the phosphor being substantially evenly dispersed within the ceramic layer.
