| 中文摘要: |
| 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. |

| Herein, Cu2SnSe3 (CTSe) nanocrystals have been synthesized by hot-injection method using a simple selenium source with Schelenk-link technology. Schlenk-line technology has been adopted. Then, Ag-doped nanocomposites have obtained by external doping monodispersed Ag nanoparticles (Ag NPs) with a size of ca. 4 nm. Then, Ag-doped nanocomposites have obtained by blending monodisperse ~4 nm Ag nanoparticles (Ag NPs). XRD, TEM, HRTEM, IR, and TG have been used to characterize CTSe nanocrystals and CTSe-Ag nanocomposites. Thermoelectric properties of the obtained CTSe nanocrystals and CTSe-Ag nanocomposite have been investigated. Relevant test results indicate that sample Cu2SnSe3-1% mol Ag shows the highest figure-of-merit ZT (ZT=0.23, 655 K) among CTSe-based samples. |
