Description
Summary:•1-phenyl-3-methyl-4-(1′-azo-2′-sodium carboxylate)-pyrazole-5-one films are grown.•Laser-based processing techniques are presented and discussed.•The influence of a metallic dynamic release layer during LIFT is emphasized.•The structure, morphology and optical properties of the films/pixels are discussed. The use of laser-based processing is presented here for the transfer of azo-derivatives, for optoelectronics assembly applications. Laser-printing techniques are also adequate tools for rapid prototyping of diverse materials, since they avoid the usage of solutions, moulds, lithography masks, etc. Here, we present a study on the laser-induced forward transfer (LIFT) and printing of micrometric-sized pixels (350μm×350μm), by using matrix-assisted pulsed laser evaporation (MAPLE) deposited thin film donors. Due to their particular optical properties, i.e. second harmonic generation, optical limiting and all-optical poling, and with applications in optoelectronics and sensor development, azo-dyes have been intensively studied in bulk or as thin films. The influence of a metallic dynamic release layer (DRL) during LIFT is investigated.
