ALLOYED SEMICONDUCTOR QUANTUM DOTS AND CONCENTRATION-GRADIENT ALLOYED QUANTUM DOTS, SERIES COMPRISING THE SAME AND METHODS RELATED THERETO

摘要

An alloyed semiconductor quantum dot comprising an alloy of at least twosemiconductors, wherein the quantum dot has a homogeneous composition and ischaracterized by a band gap energy that is non-linearly related to the molarratio of the at least two semiconductors; a series of alloyed semiconductorquantum dots related thereto; a concentration-gradient quantum dot comprisingan alloy of a first semiconductor and a second semiconductor, wherein theconcentration of the first semiconductor gradually increases from the core ofthe quantum dot to the surface of the quantum dot and the concentration of thesecond semiconductor gradually decreases from the core of the quantum dot tothe surface of the quantum dot; a series of concentration-gradient quantumdots related thereto; in vitro and in vivo methods of use; and methods ofproducing the alloyed semiconductor and concentration-gradient quantum dotsand the series of quantum dots related thereto.
