Abstract

A semiconductor nanocrystal structure may include a core, an inner absorption shell surrounding the core, at least one emission shell surrounding the inner absorption shell, and an outer absorption shell surrounding the emission shell(s). The core may include a different material than the optional inner absorption shell and/or the outer absorption shell. The core may be less absorbent to electromagnetic radiation as compared to the optional inner absorption shell and/or the outer absorption shell. An optoelectronic device may include the semiconductor nanocrystal structure.
