| 摘 要： | 根据Mie散射理论，研究了金属纳米颗粒镶嵌在载体介质中的复合薄膜的光吸收特性，计算得到Cu的介电常数与波长的关系．结果表明：当金属介电常数的虚部ε2变化不大时，复合薄膜的共振吸收峰峰位决定于金属介电常数的实部ε1和载体介质的折射率nd．

| Abstract: | Optical absorption characteristics of nanometer-sized metal particles dispersed composite thin films are investigated based on the Mie scattering theory. The relationship between permittivity of Cu and wavelength is obtained. The results show that the position of resonant absorption peak depends on the real part of the metal permittivity and the refractive index of the matrix when the imaginary part of the metal permittivity changes slightly. |
