SEMICONDUCTOR NANOPARTICLE PHOSPHOR

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor nanoparticle phosphor excellent in controllability of emission wavelength and obtaining a desired luminescent color. SOLUTION: The semiconductor nanoparticle phosphor includes two or more emitting regions independently presents different quantum effects and a barrier region and has a laminated structure in which the two or more emitting regions are isolated by the barrier region, wherein the two or more emitting regions have the same quantum level across the barrier region.
