摘要	Single crystalline tri-wing tellurium nanoribbons with well-defined outer surfaces and geometrical shapes are synthesized by a facile hydrothermal method in the presence of poly(vinyl alcohol) as the surfactant. The tri-wing Te nanoribbons with a length of tens of micrometres have a very thin wing structure with an average thickness about 20 nm. A two-step growth mechanism is proposed for the formation of tri-wing Te nanoribbons based on time dependent morphology evolution. By adjusting the pH value of the reaction solution, varied Te nanostructures including nanofeathers, nanobelts, tri-wing nanoribbons and nanorods are obtained, indicating that the reduction rate plays a key role in fabricating tri-wing Te nanoribbons since the pH value has a dramatic influence on the reduction reaction rate of TeO32-. With tri-wing Te nanoribbons as the precursor and template, Ag2Te nanoribbons in the same shape and similar size are synthesized through the direct reaction of Te with AgNO3 at room temperature, demonstrating that the Te nanoribbons with a very thin tri-wing structure are ideal templates to synthesize other Te related nanocompounds.
