| description | <p>Abstract</p> <p>A simple and mild wet-chemical approach was developed for the synthesis of one-dimensional (1D) In(OH)<sub>3</sub> nanostructures. By calcining the 1D In(OH)<sub>3</sub> nanocrystals in air at 250 °C, 1D In<sub>2</sub>O<sub>3</sub> nanocrystals with the same morphology were obtained. TEM results show that both 1D In(OH)<sub>3</sub> and 1D In<sub>2</sub>O<sub>3</sub> are composed of uniform nanotube bundles. SAED and XRD patterns indicate that 1D In(OH)<sub>3</sub> and 1D In<sub>2</sub>O<sub>3</sub> nanostructures are single crystalline and possess the same bcc crystalline structure as the bulk In(OH)<sub>3</sub> and In<sub>2</sub>O<sub>3</sub>, respectively. TGA/DTA analyses of the precursor In(OH)<sub>3</sub> and the final product In<sub>2</sub>O<sub>3</sub> confirm the existence of CTAB molecules, and its content is about 6%. The optical absorption band edge of 1D In<sub>2</sub>O<sub>3</sub> exhibits an evident blueshift with respect to that of the commercial In<sub>2</sub>O<sub>3</sub> powders, which is caused by the increasing energy gap resulted from decreasing the grain size. A relatively strong and broad purple-blue emission band centered at 440 nm was observed in the room temperature PL spectrum of 1D In<sub>2</sub>O<sub>3</sub> nanotube bundles, which was mainly attributed to the existence of the oxygen vacancies.</p> |
