Materials, Vol. 7, Pages 7243-7275: PbSe-Based Colloidal Core/Shell Heterostructures for Optoelectronic Applications (Materials)

Lead-based (IV-VI) colloidal quantum dots (QDs) are of widespread scientific and technological interest owing to their size-tunable band-gap energy in the near-infrared optical region. This article reviews the synthesis of PbSe-based heterostructures and their structural and optical investigations at various temperatures. The review focuses on the structures consisting of a PbSe core coated with a PbSexS1-x (0
