About

Materials processing technologies which imply the presence of laser radiation are versatile, rapid, allow high spatial resolution, and ensure reproducibility. Laser-matter interactions involve the development of a huge number of complex physical and chemical mechanisms, leading to materials transformations which cannot be obtained by conventional techniques. The aim of our work is to obtain nanostructured functional materials by means of different laser techniques such as Pulsed Laser Deposition (PLD), Matrix Assisted Pulsed Laser Evaporation (MAPLE), Laser Direct Write (LDW), and Laser Surface Processing (LSP). We develop high quality thin films of organic-inorganic nanocomposites and nanostructures such as semiconductor quantum dots, carbon nanotubes and graphene-based composites using MAPLE and PLD techniques. We are also investigating the chemical transformation by LSP of complex systems made of carbon-based nanomaterials, and the recrystallization of different types of nanostructures for energy, environmental, electronics and sensing applications. The experimental work, synthesis of the materials and their compositional-structural characterisation is complemented with computer simulations of the laser-matter interactions. The LPR Group leaders obtained the "International Association of Advanced Materials Scientist Medal (IAAM Scientist medal) for the year 2016" due to their contribution in the field of "Advanced Materials Science and Technology"
