采用溶剂热法合成了阳离子合金化的三元PbxSn1−xS半导体纳米晶。利用光学和结构表征测量来分析纳米晶体。指出了晶体结构和带隙能的几个有趣的变化。用前驱体反应活性的差异解释了这一现象。
Cation-alloyed ternary PbxSn1−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.
