摘要
The luminescence behavior of a PbS quantum dots (QD) in the near-IR spectral range was investigated. The PbS QDs were prepared using a water-based synthesis. The x-ray diffraction, and transmission electron microscopy (TEM) were used to study the optical properties of the QDs. The quantum dots combined stable, spectrally tunable luminescence from 1000 to 1400 nm. the fluorescent tags were observed to have a high quantum yield of photoluminescence and efficiencies that were largely independent of environment.
