Solvothermal synthesis, stirring-assisted assembly and photoelectric performance of Te nanowires.

Tellurium nanowires (NWs) are attractive one-dimensional materials for many applications, yet most synthesis processes require hazardous chemical reducing agents and extreme operating conditions. Here we described a solvothermal synthesis of Te NWs using a non-toxic reducing agent, ascorbic acid. Then the Te NWs were assembled into a well-aligned film through a stirring-assisted oil-water-air interface assembly method and a Te NWs photodetector was fabricated which is sensitive to infrared radiation.
