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. 英文摘要: 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. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1 意见回复附件1 回复 -->
