Laser beams are powerful tools for diagnostic purposes and growth of thin films. However, the interaction of lasers with organic or biological materials may result in laser-induced photo-chemical and photo-thermal damage to the materials of interest. In order to reduce these effects, the matrix-assisted pulsed laser evaporation (MAPLE) technique was introduced for thin film deposition with the possibility to use two different wavelength ranges to induce target ablation: laser absorption by the matrix (UV-MAPLE) or direct laser excitation of vibrational frequency of the matrix constituent bonds (RIR-MAPLE). In this chapter, the UV-MAPLE physical working principles will be outlined together with its applications and latest results. The RIR-MAPLE working principle and applications to materials of interest for optoelectronics applications will be described and discussed also, with particular attention to the emulsion-based RIR-MAPLE approach relating the film properties with the physical-chemical properties of the emulsion components (primary and secondary solvent, surfactant and matrix).

Abstract

Laser beams are powerful tools for diagnostic purposes and growth of thin films. However, the interaction of lasers with organic or biological materials may result in laser-induced photo-chemical and photo-thermal damage to the materials of interest. In order to reduce these effects, the matrix-assisted pulsed laser evaporation (MAPLE) technique was introduced for thin film deposition with the possibility to use two different wavelength ranges to induce target ablation: laser absorption by the matrix (UV-MAPLE) or direct laser excitation of vibrational frequency of the matrix constituent bonds (RIR-MAPLE). In this chapter, the UV-MAPLE physical working principles will be outlined together with its applications and latest results. The RIR-MAPLE working principle and applications to materials of interest for optoelectronics applications will be described and discussed also, with particular attention to the emulsion-based RIR-MAPLE approach relating the film properties with the physical-chemical properties of the emulsion components (primary and secondary solvent, surfactant and matrix).
