摘要：
Multilayered structures of gold nanoparticles (AuNPs) embedded ZnO films were prepared by sandwiching Au nanoparticles in between magnetron sputtered ZnO films. More than 80% transmittance in visible region was observed for ZnO film. For structures consisting of single and double layers of AuNPs, transmittance at similar to 600 nm was reduced to similar to 25% and similar to 6%, respectively. AuNPs embedded sandwiches showed a huge reduction in UV Photoluminescence that was prominent in pure ZnO films, and was attributed to the interband absorption in Au.
