摘要： A method for synthesizing a metal chalcogenide nanocrystal (NC) material includes reacting a metal material and an ammonium chalcogenide material in an organic solvent material. The method provides that the metal chalcogenide nanocrystal material may be synthesized by a heating-up method at large scale (i.e., greater than 30 grams). Ammonium chalcogenide salts exhibit high reactivity and metal chalcogenide nanocrystals can be synthesized at low temperatures (i.e., less than 200° C.) with high conversion yields (i.e., greater than 90 percent).

摘要： In certain embodiments, a first semiconductor material is vaporized to generate a vapor phase condensate. The vapor phase condensate is allowed to form nanoparticles. The nanoparticles are annealed to yield nanoparticles or cores. The cores are overcoated by introducing a solution containing second semiconductor material precursors in a coordinating solvent into a suspension of cores at a desired elevated temperature and mixing for a period of time sufficient to cause diffusion of the shell into the core. The diffusion of the shell into the core causes the quantum dots to exhibit a broadened optical emission. The produced quantum dots may be incorporated into a quantum dot based radiation source.

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.
