Timehyphen;resolved emission spectroscopy of the highTcsuperconductor YBa2Cu3O7minus;xunder laser ablation

摘要

Timehyphen;resolved luminescence spectroscopy is described for highTcYBa2Cu3O7minus;xunder 8 ps/530 nm laser ablation. The emission spectrum covered most of the visible spectrum and showed emission lines from ions. The emission profiles in time consist of fast (ape;25 ps) and slow (ape;1 ns) decay components.
