| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 97 === The aim of this research is to prepare boron nitride (BN) nanotubes by evaporating the target composed of the carbon rod and tungsten bulk via modified plasma arc gas technique. The effects of the chamber pressures and electrodes on the synthesis of BN nanomaterials were also studied.
The results show that the yields of the BN nanotubes are inverse-proportional to the chamber pressures, particularly at 400 Torr. With XRD data, the as-prepared materials are o-BN phase with growth plane of (211). Many co-existence structures can be observed by FT-IR measurement. The band gap of BN nanotubes are 4.28~4.37 eV estimated by UV-visible spectrum. The PL peaks are shown in ultra-violet (373nm) and blue range (469nm、470nm).
