What is it about?
The defects and film thickness play a major role in the optical properties of plasmonic devices. Here we studied the electronic and optical properties of ZnO-Au composites using synchrotron radiation based X-ray absorption spectroscopy and photoluminescence spectroscopic techniques.

Why is it important?
ZnO with its wide direct bandgap and large exciton binding energy is a potential material for optoelectronic and spintronic applications. Detailed electronic and optical properties of ZnO/Au composites are essential for devising application.
Perspectives
In this article, a systematic characterization has been followed to understand the effective coupling of surface plasmon resonance (SPR) of Au nanoparticles with the ZnO band electrons for the enhanced optical properties of ZnO/Au hybrid films with different thickness of ZnO film. This study shows an interesting results that the SPR effect depends on the film thickness and the defects in the film. The experimental results are consistent with each other and are discussed in detail.
