A: We reports a study on pure and Ni-doped TiO 2 thin films produced via laser ablation technique. The novelty of the work consists that both synthesis and doping were carried out in a single process, using a modified laser ion source to simultaneously make pulsed laser deposition (PLD) and low-energy ion implantation (by post-acceleration method). In particular, two titania films were synthesized via PLD starting from a rutile target. One of the two films was doped with Ni ions, accelerated with a voltage of 20 kV. The total implanted dose, evaluated by a Faraday cup, resulted to be 1 × 10 14 ions/cm 2 . The crystalline phase of the obtained TiO 2 films was analysed by Raman spectroscopy. A higher photocatalytic activity, measured under UV irradiation using methylene blue, was estimated for the Ni-doped titania film with respect the pure one.

During the restoration work promoted by the FAI foundation (Fondo Ambiente Italiano) of the abbey of Santa Maria di Cerrate (Lecce, Apulia, South Italy), multidisciplinary analyses have been realized to support conservators and art historians for the safeguard and valorization of the most important byzantine evidence (12th–13th century) in Apulia. In this paper, mortar samples have been investigated using scanning electron microscopy (SEM-EDX) and X-ray diffraction (XRD) to characterize the observed materials, directing conservators for the integration interventions with compatible realizations. Moreover, the samples were compared with specimens taken from local quarries and the nearest coastline area, and vegetal fibers, embedded into the mortars were analyzed by applying radiocarbon dating by accelerator mass spectrometry (AMS). It was thus possible to give a contribution to the historical-artistic research related to the building techniques, the ratio aggregates/binder and the employed materials of the mortars and the dating of the mural paintings between the end of the 12th century and the first half of the 13th century.

We present the design and implementation of the new Ion Beam Induced Luminescence set-up recently installed and tested at the Centre of Applied Physics, Dating and Diagnostics of the University of Salento. The set-up allows the irradiation of samples at atmospheric pressure with MeV protons produced by a 3 MV Tandetron accelerator and extracted in air through a kapton membrane. Ion beam induced luminescence is collected by an optical fiber and analyzed by an imaging spectrometer. Simultaneously, characteristic X-Rays emitted by the sample are detected by a Silicon Drift Detector (SSD) detector. The system also allows combined photoluminescence measurements by using an excitation laser focused onto the samples. First applications in the analysis of all-inorganic perovskites (CsPbBr3) deposited by PLD (Pulsed Laser Deposition) are presented.
