| Outline of Final Research Achievements |
ZnO micro-spheres were synthesized by laser ablation in air using a Q-switched Nd:YAG laser. The p-n junction was fabricated with 3,4-ethylene- dioxythiophene: poly(styrenexulfonate) (PEDOT/PSS) film as a p-type organic conductor and a n-type ZnO shpere. The electrical and optical characteristics of the fabricated junction was examined. As the results, the rectifying characteristics and the EL emission were successfully observed. In some samples, the WGM mode structure was observed in the EL spectrum.
