Near-monodispersed water soluble SnS nanoparticles in the diameter range of 3-6 nm are synthesized by a facile, solution based one-step approach using ethanolamine ligands. The optimal amount of triethanolamine is investigated. The effect of further heat treatment on the size of these SnS nanoparticles is discussed. Diffuse reflectance study of SnS nanoparticles agrees with predictions from quantum confinement model.

采用一种简便的、基于溶液的一步法，使用乙醇胺配体合成了直径范围为3 - 6纳米的近单分散水溶性硫化锡纳米颗粒。研究了三乙醇胺的最佳用量。讨论了进一步热处理对这些硫化锡纳米颗粒尺寸的影响。硫化锡纳米颗粒的漫反射研究与量子限域模型的预测结果相符。
