Herein, a facile solution chemical route has been developed for synthesis of Ag₂Se-based alloy nanocrystals. The maximum thermoelectric figure of merit reaches 0.7 at 317 K for Ag₂Se, which is the largest value reported by a wet chemical method. Sn doping further improves ZT to 0.9 at 300 K, realized by the simultaneous modulation of transport and thermal properties. Our results indicate that cycling and Sn doping are efficient ways to enhance the thermoelectric performance of Ag₂Se.

通过湿化学法制备的Ag2Se基材料具有很高的热电性能

在此，已经开发了用于合成Ag ₂ Se基合金纳米晶体的简便溶液化学路线。Ag ₂ Se的最大热电品质因数在317 K时达到0.7 ，这是湿化学法报道的最大值。Sn掺杂通过同时调制传输和热性能，进一步将ZT在300 K下提高到0.9。我们的结果表明，循环和Sn掺杂是提高Ag ₂ Se热电性能的有效方法。
