Synthesis of NIR-emitting InAs-based core/shell quantum dots with the use of tripyrazolylarsane as arsenic precursorTietze, Remo, Panzer, Rene, Starzynski, Thorben, Guhrenz, Chris, Frenzel, Florian, Würth, Christian, Resch-Genger, Ute, Weigand, Jan J., Eychmüller, Alexander 02 May 2019 (has links)
Tris(3,5-dimethylpyrazolyl)arsane (1) is introduced as an low-cost and convenient to handle arsenic precursor for the straight forward synthesis of InAs quantum dots (QDs). Transamination of 1 with the solvent oleylamine (OLAH) gives trioleylarsane (As(OLA)3) which in the presence of the reducing agents DIBAL-H or P(OLA)3 yields InAs QDs via a typical hot injection approach. The size of the obtained InAs core QDs are tuned by varying the reaction time, the amount of the applied reducing agent, or even more effectively by changing the indium and/or zinc halide precursors, InX3 and ZnX2 (Cl, Br, or I). Passivation of the resulting InAs particles with a protective ZnS or ZnSe shell results in improved photoluminescence (PL) of the core/shell QDs covering a spectral range between 600–1150 nm.
