主　　题：Silver nanowires Anti-counterfeiting Infrared light Excitation-free Conformability 

摘      要：Silver nanowire(AgNW)films have been widely used as flexible transparent electrodes due to the high electrical conductance and high transmittance in the visible *** infrared(IR)properties of AgNW films,however,are seldom ***,we show that ultrathin AgNWs present high transmittance in the visible range(~95%)and high reflectance(60-70%)in the IR range of 8e14 *** a significant difference makes AgNW films invisible to naked eyes but visible under an IR camera,being an ideal selection for anti-counterfeit technologies,while no excitation is *** have demonstrated that AgNW films can be spray-coated on either flat or microstructured surfaces with high conformability and high scratch-resistance,and thus these anti-counterfeiting materials can be applied to a variety of *** AgNW-based anti-counterfeiting may be helpful for combating counterfeiting crimes in the fields of medicines,artwork,banknotes,brand luxuries,industrial parts,and so on.
