首次采用3-氨丙基三甲氧基硅烷作为连接分子，将5、10和20 nm的尺寸定向金纳米粒子（AuNPs）化学连接到铝掺杂氧化锌（Al-ZnO）衬底上。通过使用这些衬底，我们提出了不同的颗粒尺寸和颗粒间的距离沉积在Al-ZnO上的AuNPs的泵浦-探测研究。所得到的结果可能是表面等离子体共振与带内贡献的非线性光学折射率和声子的相互作用的相互作用的结果。
Size-aligned gold nanoparticles (AuNPs) of 5, 10, and 20nm were attached on aluminum-doped zinc oxide (Al–ZnO) substrates chemically using for the first time 3-aminopropyl-trimethoxysilane as a linker molecule. By using these substrates, we present the pump-probe studies of the AuNPs deposited on the Al–ZnO with the different particle sizes and inter-particle distances. The obtained results may be a consequence of interaction of surface Plasmon resonances with the intra-band contributions to the nonlinear optical susceptibilities and to the interactions with the phonons.
