light region

Some different thickness aluminum reflective films were produced on silicon substrate by using the electron-beam evaporation method and high purity aluminum target. The reflectivity curves of Al film in the visible light region were measured, the density and conductivity of films were analyzed.

采用电子束蒸发的方法，以高纯度的Al为靶材，硅片为衬底，制备了不同厚度的Al反射膜，并测量了在可见光范围内反射率曲线，分析了薄膜的致密性和电导率。

In the visible light region, the maximal one-photon absorption strengths of the molecules occur in the first excited state.

在低能量范围内，对于D-π-A型分子，分子的单光子吸收强度和双光子吸收截面最大值都发生在分子的第一激发态。

By reducing the thickness of the layer of metal cladding, the plasmon resonance wavelength can be moved from the visible light region of red to near-infrared region.

通过减小金属覆层的厚度，等离子体共振波长可以从可见光区域红移到近红外区域。
