Table 1. The fitted lifetimes of Ag nanowire, monolayer graphene and the Ag nanowire-graphene hybrid detected in the visible region, respectively; monolayer graphene and the Ag nanowire-graphene hybrid detected in the near-infrared region, respectively.

System	Spectrum range of probe light	Lifetime of fast process (τ1(fs))	Lifetime of slow process (τ2(ps))
Ag nanowire	Vis	150 ± 7 (4.4%)
Graphene	Vis	275 ± 77 (22.4%)	1.4 ± 0.3 (27.9%)
Graphene	NIR	320 ± 46 (14.5%)	2.5 ± 0.6 (22.8%)
AgNW/Graphene	Vis	534 ± 108 (20.2%)	3.2 ± 0.8 (26.1%)
AgNW/Graphene	NIR	780 ± 92 (11.8%)	3.9 ± 0.9 (24.3%)

The proportion is the deviation percentage, which ensures the accuracy of fitted parameters.
