Spectroscopic ellipsometry was used to check plasmonic properties of thin annealed gold films depending on the thickness of the annealed films and parameters of the annealing. It is demonstrated that the position of the plasmonic resonance is defined by the size of produced nanoparticles together with the strength of interparticle interactions. It is shown that the account of interparticle interactions is necessary for the correct description of optical properties of layers of plasmonic nanoparticles.

退火金薄膜的等离子特性

椭圆偏振光谱法根据退火膜的厚度和退火参数，检查薄退火金膜的等离子体性能。已经证明，等离子体共振的位置由所产生的纳米粒子的尺寸以及粒子间相互作用的强度来定义。结果表明，粒子间相互作用的考虑对于正确描述等离子体纳米粒子层的光学特性是必要的。
