碩士 === 逢甲大學 === 電子工程所 === 94 === Bi2Te3 nanowires with two diameters of 30 nm and 60 nm have been assembled into the nanopores of alumina template by electrodeposition in the solution containing Bi3+ and HTeO2+ with porous alumina template as a cathode. Scanning electron microscopy indicates that the ordered Bi2Te3 nanowire arrays are entirely filled. X-ray diffraction result shows that the as-synthesized nanowires are crystalline and have a highly (110) preferential orientation. Energy dispersive spectrometer analysis observation shows the composition ratio is very close to 2 : 3. The comparisons of the two size Bi2Te3 nanowire arrays (30 nm and 60 nm) were observed by the measurements of photoluminescence (PL) and ultraviolet-visible absorption spectroscopy (UV-vis), respectively.
