Abstract :
In this study, we optimized vertically aligned carbon nanotube electron beam (C-beam) with triode structure for cathodoluminescence of Zinc Oxide (ZnO) thin films, which solution process fabricated. Efficient cathodoluminescences were observed with C-beam exposed ZnO thin films. The origin of the luminescence were confirmed by SEM measurement. The luminescence appeared to the structural modification of thin ZnO films after C-beam exposure, resulting nano-crystalline film formation.
