Abstract

Cation-alloyed ternary Pb_xSn_1−xS semiconductor nanocrystals were synthesized via a solvothermal method. Both the optical and structural characterization measurements were utilized to analyze the nanocrystals. Several interesting variations on the crystal structures and band gap energy were indicated. The differences in reactivity of precursors were employed to explain the phenomenon.
