摘要：Cu2SnSe3 (CTSe) nanocrystals were synthesized by Schlenk-line technology through a simple method of hot-injection of selenium source. Then Ag-doped nanocomposites with a size of ca. 4 nm were obtained by external doping monodispersed Ag nanoparticles (Ag NPs). XRD, TEM, HRTEM, IR, and TG were used to characterize CTSe nanocrystals and CTSe-Ag nanocomposites. Thermoelectric properties of as-obtained CTSe nanocrystals and CTSe-Ag nanocomposites were investigated. Relevant test results indicated that sample CTSe-1 (mol) % Ag showed the highest figure-of-merit ZT (ZT=0.23, 655 K) among different ratio CTSe-Ag samples.
