In recent years, energetic heavy ions have been used to modify the physical properties of various materials [1]. In this study, we investigate the influence of irradiation of molybdenum trioxide (MoO3) thin films with MeV ions of various parameters [2]. The films were deposited on fused silica using thermal evaporation technique. After irradiation, the films were characterized using optical spectroscopy and XRD techniques, showing the effectiveness of ion-irradiation in tuning the films optical and structural properties by varying ion beam parameters. This is highly important for the design of advanced metal oxide materials for sensing, switching, and energy applications.
