Abstract:Bi2Te3 has been extensively used because of its excellent thermoelectric properties at room temperature. Here, 230–420 nm of Bi2Te3 hexagonal nanosheets has been successfully synthesized via a “green” method by using ethylene glycol solution and applying polyvinyl pyrrolidone (PVP) as a surfactant. In addition, factors influencing morphological evolution are discussed in detail in this study. Among these parameters, the reaction temperature, molar mass of NaOH, different surfactants, and reaction duration are … Show more
