摘要： A novel quantum dot capable of near infrared emissions at wavelengths of 750-1100 is made by forming solid solutions of metal sulfide, metal selenide or metal sulfide selenide by incorporating a suitable amount of an additional metallic element or elements to provide an emission wavelength in the range of 750 nm to 1100 nm. The quantum dots may be enabled for bioconjugation and may be used in a method for tissue imaging and analyte detection.

摘要： An economic, direct synthetic method for producing water soluble ZnS QDs that are ready for bioconjugation is provided. The method can produce aqueous ZnS QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. The aqueous ZnS QDs are stable in biological fluids over a long period of time. In addition, non-toxic ZnS QDs have been produced with good photoluminescence properties.
