采用反应射频磁控溅射法在750 °C下制备了镶嵌有Ag纳米颗粒的ZnO薄膜。薄膜的光致发光发射强度和入射光的消光系数有很大的提高。这种增强被认为是由于Ag纳米颗粒中局域表面等离子体激元与光的相互作用。薄膜中的表面等离子体激元可以在很宽的范围内激发，从紫外到近红外波长的光。
ZnO films embedded with Ag nanoparticles are deposited at 750 °C with a reactive radio-frequency magnetron sputtering. The films are found to have a large enhancement in the intensity of photoluminescence emission and in the extinction of incident light. The enhancement is assigned to be from the interaction between the localized surface plasmons in the Ag nanoparticels and the light. The surface plasmons in the films can be excited in a wide range, from ultraviolet to near infrared wavelength of light.
