| Abstract: | The effects of excimer laser irradiation on the surface structure and luminescence of sintered ZnO ceramics were investigated. Photoluminescence spectra of three materials (as-prepared ZnO ceramic, the ceramic blackened by high-energy irradiation and the recovered ceramic treated using lower-energy irradiation) were compared in the visible region at room temperature and 10 K. Each material exhibited a green luminescence band but the blackened ZnO ceramics had the strongest emission in the visible region while the recovered ceramics had significantly shorter decay times. |
