Abstract
Lighting apparatus including a light emitting diode and a plurality of semiconductor structures. Each semiconductor structure includes a quantum dot comprising a nanocrystalline core comprising a first semiconductor material and a nanocrystalline shell comprising a second, different, semiconductor material at least partially surrounding the nanocrystalline core, the quantum dot having a photoluminescence quantum yield (PLQY) of at least 90%. An insulator layer encapsulates the quantum dot.
