Preparation and characterization of sol-gel Li and Al codoped ZnO thin films |
| 초록 |
Li and Al codoped ZnO (LAZO) thin films have been prepared by a sol-gel method and their structural and optical properties have been investigated. The films prepared had an average transmittance over 85% in the visible range. The UV absorption edge was red-shifted with Li-doping, whereas it was blue-shifted with Al-doping. The optical energy gap Eg was dependent on dopant concentration. Broad-band yellowish-white emission was observed to cover nearly the whole visible range. The visible emission was enhanced with increasing annealing temperature and dopant concentration. |
