Abstract: A light emitter is a light emitter for converting incident electrons into light, and includes a multiple quantum well structure for generating the light by incidence of the electrons, and an electron incident surface provided on the multiple quantum well structure. A certain barrier layer included in a plurality of barrier layers constituting the multiple quantum well structure is thicker than another barrier layer included in the plurality of barrier layers and located on the electron incident surface side with respect to the certain barrier layer.

Abstract: There are provided a light-emitting element, an optical detection module, a method for manufacturing a light-emitting element, and a scanning electron microscope using the same, by which it is possible to reduce crosstalk and expand the range of applications. A light-emitting element includes a fiber optic plate substrate having transparency to fluorescence and a light-emitting layer as a nitride semiconductor layer having a quantum well structure. In the light-emitting element, the fiber optic plate substrate and the light-emitting layer are directly bonded to each other.
