    Abstract: A light receiving element includes a p-type semiconductor layer, an n-type semiconductor layer, and a first and a second superlattice semiconductor layers, and the first and the second superlattice semiconductor layers each have a superlattice structure in which a barrier layer and a quantum dot layer are alternately and repeatedly stacked. A band structure of the superlattice structure of the first superlattice semiconductor layer is a type I structure, and that of the second superlattice semiconductor layer is a type II structure. The superlattice structures of the first and the second superlattice semiconductor layers each form a superlattice miniband, and a conduction band first superlattice miniband of the superlattice structure of the second superlattice semiconductor layer is lower in lower and energy than a conduction band first superlattice miniband of the superlattice structure of the first superlattice semiconductor layer.

    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.
