Abstract
A light-emitting device includes a photoluminescent layer that emits light containing first light, a light-transmissive layer located on or near the photoluminescent layer, and one or more reflectors. A submicron structure is defined on at least one of the photoluminescent layer and the light-transmissive layer. The one or more reflector are located outside the submicron structure. The submicron structure includes at least projections or recesses and satisfies the following relationship:λ<λwhere Dis a center-to-center distance between adjacent projections or recesses, λis the wavelength of the first light in air, and nis the refractive index of the photoluminescent layer for the first light.
