Enhancement effect of UV light emission by ZnO/Au film on flexible structures

摘要

We investigated the optical properties of ZnO/Au film structures fabricated by sputtering and spin coating. The PL intensity of the ZnO/Au was larger than that of a ZnO thin film by up to one orders of magnitude. The spectral dependence of the PL intensity was also well supported by the experimental reflectance spectra and the electric field distribution at the ZnO/Au interface.
