Many domains, such as biomedical, micro-fluidic or quantum optics, applications are in need of nanoparticles with specific optical properties. Laser ablation in liquid PLAL is a synthesis method that can rapidly screen nanoparticles in a wide range of materials, and thus test the preservation or modification of the optical properties, identified in the bulk material, when downsizing to nanometers (scintillation, thermo-luminescence, photo-stimulation, high luminescence efficiency ...). In this work doped nanoparticles were synthesized and characterized both optically and structurally. Different materials were tested, including doped gadolinium oxide, yttrium aluminum garnet (YAG), alumina etc. This showed the feasibility and potential of this technique developed on different materials. Also this research activity is focused on the development of a diagnostic tool for plasma, by time-resolved optical spectroscopy, to understand the growth process of the particles formed.
