Abstract
The most desirable features of PbS nanocrystal (NC) synthesis are demonstrated in a new one‐stage route: Aqueous synthesis to enable compatibility with biological assays and polymer–nanocrystal device fabrication; simplicity; non‐toxic solvents; and moderate reaction temperatures. The NCs produced (see Figure) have stable, narrow fluorescence peaks that are size‐tunable in the near‐IR spectral range and a high quantum yield.Keywords
