  text: We present a high-yield and scalable colloidal synthesis to produce monodisperse
    AgSbSe2 nanocrystals (NCs). Using nuclear magnetic resonance (NMR) spectroscopy,
    we characterized the NC surface chemistry and demonstrate the presence of surfactants
    in dynamic exchange, which controls the NC growth mechanism. In addition, these
    NCs were electronically doped by introducing small amounts of bismuth. To demonstrate
    the technological potential of such processed material, after ligand removal by
    means of NaNH2, AgSbSe2 NCs were used as building blocks to produce thermoelectric
    (TE) nanomaterials. A preliminary optimization of the doping concentration resulted
    in a thermoelectric figure of merit (ZT) of 1.1 at 640 K, which is comparable
    to the best ZT values obtained with a Pb- and Te-free material in this middle
    temperature range, with the additional advantage of the high versatility and low
    cost associated with solution processing technologies.
