摘要
Ag nanoparticles with a narrow size distribution down to 3-4 nm have been embedded in an Al2O3 matrix by a single step pulsed laser co-deposition. A two-beam laser setup and a single target which is composed of Ag and Al2O3 are used for achieving a controlled deposition. This approach allows the control of the laser fluency on each target independently. The resulting Ag/Al2O3 nanocomposite thin films exhibit a specific plasmon absorption. This easy-to-apply single step method allows precise particle size and distribution control at room temperature. Therefore the approach can be used for synthesis of various nanocomposite thin films of more complex materials on various substrates.
