岛膜的金的光吸收作为岛密度的函数，从电子显微镜照片和膜厚度确定进行了研究。随着岛密度的增加，粒子中有界等离子体共振产生的吸收带向更长的波长移动。带的位置是预测的麦克斯韦加内特理论的岛屿膜与球形颗粒。随着粒子变小，吸收带变宽，因为其中电子的平均自由程减小。
The optical absorption of island films of gold was studied as a function of island density, as determined from electron micrographs and film thickness. The absorption band resulting from a bounded plasma resonance in the particles was shifted to longer wavelengths as the island density increased. The position of the band was that predicted by the Maxwell Garnett theory for island films with spherical particles. As the particles became smaller the absorption band was broadened because the mean free path of the electrons in them was reduced.
