Abstract

The disclosed light emitter converts an incident electron beam into fluorescence. The light emitter comprises: a substrate that is transparent to fluorescence; and a quantum well structure formed on one surface of the substrate, which emits fluorescence upon incident electron beam. The quantum well structure comprises: a first wavelength layer that emits the aforementioned fluorescence of a first wavelength upon incident electron beam; and a second wavelength layer deposited on the first wavelength layer that emits fluorescence of a second wavelength shorter than the first wavelength upon incident electron beam.
