我们回顾了我们最近的贡献，使用溶剂热方法制备不同的氧化物和硫属化物纳米粒子。我们已经制备了亚10纳米，γ-Fe 2 O3 ZnFe 2 O 4，和CoFe 2 O 4粒子的分解相应的铜铁试剂配合物的存在下，正辛胺或正十二胺在溶剂热甲苯。类似地，通过在溶剂热条件下使硬脂酸镉与H2Se反应来制备十二硫醇封端的CdSe硫族化物纳米颗粒。H2Se是通过四氢萘还原Se原位生成的。使用后一种技术，我们也已经能够在溶剂热条件下在甲苯中制备PbSe和PbI 2，尽管是散装（而不是纳米晶）形式。在制备PbI 2时，HI是通过四氢萘原位还原I-2制备的。
We review our recent contributions to the use of solvothermal methods for the preparation of different oxide and chalcogenide nanoparticles. We have prepared sub 10-nm,gamma-Fe2O3 ZnFe2O4, and CoFe2O4 particles by the decomposition of the corresponding cupferron complexes in the presence of n-octylamine or n-dodecylamine in solvothermal toluene. Similarly, dodecanethiol-capped chalcogenide nanoparticles of CdSe have been prepared by reacting cadmium stearates with H2Se under solvothermal conditions. The H2Se is generated in situ by the reduction of Se by tetralin. Using this latter technique, we have also been able to prepare PbSe and PbI2 in toluene under solvothermal conditions, albeit in bulk (rather than nanocrystalline) form. In the preparation of PbI2, HI is prepared by the in situ reduction of I-2 by tetralin.
