摘要: This paper introduces a facile and effective route to decorate micro-sized silver particle surfaces with Ag/AgI nanoclusters through wet chemical reaction at room temperature using iodine ethanol as reactant solvent, respectively. Photosensitivity of AgI is utilized in the route, decomposes into Ag upon contact sunshine, forming nanoclusters. The modified particles showed sinterability even 200°C formed rigid electrical conductive networks 350°C. Moreover, sintered film containing reached best conductivity, 9.35 mΩ/sq, after sintering 350°C for 20 min, while untreated control obtained its conductivity 400°C. excellent should be attributed which served aid during heating process. However, increase time destroyed densification particles.
