InAs Colloidal Quantum Dots Synthesis via Aminopnictogen Precursor Chemistry

摘要: Despite their various potential applications, InAs colloidal quantum dots have attracted considerably less attention than more classical II-VI materials because of complex syntheses that require hazardous precursors. Recently, aminophosphine has been introduced as a cheap, easy-to-use and efficient phosphorus precursor to synthesize InP dots. Here, we use aminopnictogen precursors implement similar approach for synthesizing We develop two-step method based on the combination aminoarsine arsenic reducing agent. This results in state-of-the-art with respect size dispersion band gap range. Moreover, present shell coating procedures lead InAs/ZnS(e) core/shell emit infrared region. innovative synthesis can greatly facilitate research may protocols wide range III-V
