Laser-induced scanning transfer deposition of silver electrodes on glass surfaces: A green and scalable technology

A pulsed laser ablation backwriting technique with high repetitive rates is implemented for the fabrication of silver coatings on glass surfaces. This method enables geometrical constraint-free deposition metallic coatings. These exhibit sufficiently low electrical resistance to be used as electrodes in dielectric barrier discharge (DBD) plasma elements. Ambient air standard slides explored using a sub-ns UV source, combined hybrid beam scanning methods. The green nature overall process includes preliminary irradiation scan homogenise target surface before subsequent step. Metal transfer achieved by combining two phenomena within simple process: LIRT (laser-induced reverse transfer) from glass, partial and secondary LIFT (Laser-Induced Forward Transfer) target. Appropriate selection pulse energy repetition rates, velocities motion enable growth thick Ag deposits required resistivity nearly 2D geometry. avoids use vacuum liquids, resulting cheap, facile methodology onto transparent substrate
