In this HOT article, Chinese researchers have demonstrated for the first time that ternary cation-alloyed PbSnS nanocrystals could be synthesized via a facile solution-based routine. The mean diameters of the as-prepared nanocrystals ranged from 6–15 nm. Several interesting variations on the crystal structure and band gap energy were indicated. The results could potentially have a high impact on IV-VI quantum dots based optoelectronic applications in the future.
