7. The original gold weight concentration in toluene gold nanoparticle solution was 30%. However, due to the evaporation of the toluene in the reservoir of the jetting head, the gold weight concentration increased up to about 34(±1)% during the operation of the jetting. Therefore, 30%-35% of the gold weight concentration was used for the calculation.
8. To prevent the direct heating of laser on the transparent substrate, the laser at the visible wavelength was selected. In addition, due to the small absorption depth of the nanoparticle ink on the wavelength of the incoming laser radiation (Ref. 6), when the laser is directly irradiated to the printed ink, most of the radiation will be absorbed in the close vicinity of the free surface of printed line.

10. 2/μα where γ, μ, and α are the thermal gradient of surface tension, viscosity and thermal diffusivity of pure toluene, respectively. The width of the displaced U-shaped ink [Fig. 1(b)] was used for L and the difference between the evaporation temperature of toluene and the room temperature was used for ΔT. The value of 5-10 μm was used for H.
