Formation of Ce doping β-Ga2O3 nanofiber by electrospinning and evaluation of optical band gap energy and photocatalytic properties. |
| 초록 |
Ce doped β-Ga2O3 nanofibers were prepared using a derived electrospinning, by varying the Ce mol% from 0 to 1.0 to evaluate the effect of Ce doping on optical band gap, and photocatalytic. Materials properties of Ce doped β-Ga2O3 nanofibers are characterized using X-ray diffraction, scanning electron microscopy, UV-vis spectrophotometry. The β-Ga2O3 peak became broader and weaker with increasing Ce amount. UV-vis spectrophotometry results showed that the values of Eg decreased from 4.93 eV to 4.49 eV with the increase of Ce doping from 0 to 0.7mol%. But, increased to 4.69 eV when Ce content was 1.0mol% and the photo-degradation performance of MB (methylene blue) also observed the same tendency. Experimental results indicated that the Ce doping was mainly attributed to the optical band gap energy of Ce doped β-Ga2O3 and the photocatalytic degradation of organic dye. |
