摘要：

We show that oxidation of protective thiol ligands and the exothermic reduction of surface area are important factors in the sintering of thiol-stabilized gold nanoparticle films. We also present a chemical treatment to achieve sintering of gold nanoparticles at room temperature. The process is facilitated by the remarkable enthalpy of reaction arising from the reduction of the surface area of the nanoparticles.
