摘要：

An ultrafast nonlinear optical Kerr response as fast as 190 fs is reported for mesoporous-silica-composite thin films loaded with highly dispersed gold nano-particles. These are synthesized by a newly developed strategy, in which gold is introduced into the mesochannels of the silica by a surface-modification scheme coupled with a neutralization reaction route (see Figure).
