Laser induced forward transfer of silver nanoparticles patterns

Abstract

Laser-induced forward transfer (LIFT) with fs-pulses is used to produce silver nanoparticles patterns on glass substrates. LIFT is a versatile direct laser write technique in which a variety of materials can be transferred from a donor substrate to a receiver one. Here we present a study on the optimal parameters, such as scan speed and pulse energy, required to obtain a micrometric pattern on the transfer process. Spectroscopy analyses confirmed the composition and the formation of silver nanoparticles. Also, the electron microscopy image revealed a controlled and localized deposition of silver nanoparticles, indicating such approach as a promising technique for the development of applications from electronics to photonics.
