چکیده انگلیسی
Using Indium acetylacetonate as single-source precursor, In2O3 nanotube arrays have been synthesized within the pores of the porous anodic alumina (PAA) membranes by chemical vapor deposition (CVD) at low temperature. The nanotubes with an outer diameter of about 100-300Â nm and a length of up to tens of microns were characterized using scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopic analyzer (EDS), X-ray diffractometer (XRD) and transmission electron microscopy (TEM), respectively. A novel Y-branched structure and the quasi-hemispherical ends were also observed. A blue-green emission band centered at 475Â nm was observed in the photoluminescence spectrum of the In2O3 nanotube arrays, which could be ascribed to the existence of oxygen vacancies.
