Abstract
Many embodiments implement quantum confined nanoplatelets (NPLs) that can be induced to emit bright and tunable infrared emission from attached quantum dot (QD). Some embodiments provide mesoscale NPLs with a largest dimension of greater than 1 micron. Certain embodiments provide methods for growing mesoscale NPLs and QD on mesoscale NPLs heterostructures. Several embodiments provide near unity energy transfer from NPLs to QDs, which can quench NPL emission and emit with high quantum yield through the shortwave infrared. The QD defect emission can be kinetically tunable, enabling controlled mid-gap emission from NPLs.
