Abstract: A phosphor plate includes a base material, a phosphor and a scattering material. The phosphor absorbs primary light emitted by a light emitting element and emits secondary light having a wavelength longer than a wavelength of the primary light. The scattering material scatters the primary light and the secondary light. An average distance from one surface of the phosphor plate to the phosphor is longer than an average distance from the one surface to the scattering material. With such a configuration, there are provided a phosphor plate having the enhanced extraction efficiency of light emitted by a phosphor, a light emitting device including the phosphor plate, and a method for manufacturing the phosphor plate.

Abstract: The occurrence of a color irregularity in light that is emitted from a light-emitting device is suppressed together with being able to prevent a decline in the utilization efficiency of excitation light. A light-emitting device is provided with a phosphor section that absorbs excitation light and emits first fluorescence, and a phosphor section that absorbs excitation light that has passed through the phosphor section without being converted into first fluorescence by the phosphor section and emits second fluorescence. Also, the peak wavelength of the second fluorescence is approximate to the peak wavelength of the excitation light.

Abstract: A light emitting device is provided that includes a light emitting element emitting primary light, and a wavelength conversion portion provided on the light emitting element, absorbing a part of the primary light and emitting secondary light, in which the wavelength conversion portion is made of a plurality of resin layers including at least a first wavelength conversion portion made of a resin layer containing a rare earth-activated phosphor or a transition metal element-activated phosphor, and a second wavelength conversion portion made of a resin layer containing a nanocrystalline phosphor. The first wavelength conversion portion is disposed closer to the light emitting element than the second wavelength conversion portion is.According to the light emitting device, it becomes possible to prevent a substrate from discoloring due to reaction of a silver part of the light emitting device with a nanocrystalline phosphor, thereby preventing a decrease in light emitting efficiency.
