Special Issue Information

Dear Colleagues,

Pulsed laser ablation has already proved to be a versatile and powerful way for the preparation of a great variety of materials. This method has been shown to be suitable not only to deposit thin films (PLD), often maintaining stoichiometry and properties of bulk targets, but also in order to obtain products with peculiar properties that in some cases are quite different from those of the starting material. Indeed, apart from PLD, laser ablation performed in liquid media (PLAL) is corrently used as a simple and clean method  to produce nanoparticles (NPs) and nanostructures. In recent years, the use of high-repetition-rate ultrashort pulse lasers to modify and functionalize the surfaces of bulk materials and thin films has opened a new field of possible applications ranging from electronics to biomimetic materials.

The topics of interest to this Special Issue include but are not limited to the following:

  • ns and fs PLD of thin films of materials for biological applications;
  • ns and fs PLD of thin films of ceramic materials and of protective coatings;
  • Applications of PLD to materials in the field of energy storage;
  • Multilayered films produced by PLD;
  • Mixed deposition tecniques including PLD;
  • NPs and nanostructures produced by PLAL;
  • Laser produced NPS for plasmonic applications;
  • Laser production of NPs and thin films for SERS applications;
  • Doping of glasses by metallic NPs produced by laser tecniques;
  • Surface modification and patterning by fs ablation.

Chromium borides are promising candidates for several structural applications including protective coatings for materials exposed to corrosive and abrasive environments. In this paper the pulsed laser deposition of chromium diboride-rich thin films has been carried out in vacuum by using a frequency doubled Nd:glass laser with a pulse duration of 250 fs. The films have been deposited at different substrate temperatures and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. Lastly, the film’s hardness has been studied by Vickers indentation technique. The results indicate that only the films deposited at a substrate temperature of 500 °C are crystalline and formed by chromium diboride, together with a certain amount of boron and chromium, which suggests that, as main mechanism, a process taking place on the surface from atoms and ions from the gas phase. This hypothesis has been confirmed by the study of the plasma produced by the ablation process. Full article

Ultra-Short Pulsed Laser Deposition of Oxides, Borides and Carbides of Transition Elements

Oxides, borides and carbides of the transition elements are materials of great interest from a technologic point of view. Many of these materials are used in the form of thin films, so several techniques are commonly used to deposit them. Among these techniques, Pulsed Laser Deposition (PLD) performed using ultra-short pulse lasers, mainly fs lasers, presents unique characteristics in respect to PLD performed using conventional short pulse lasers. Indeed, the films deposited using fs PLD are often nanostructured, and this technique often allows the target stoichiometry to be transferred to the films. In this work, we will review the use of ultra-short PLD in the production of films obtained from transition metal oxides, borides and carbides, evidencing the advantages offered by this technique, together with the problems arising with some of the studied systems. We conclude that even if ultra-short PLD is surely one of the most important and useful deposition techniques, it also presents limits that cannot be ignored. Full article
