Title: Improved optical and electrical properties of 200 MeV Ag{sup 15+} irradiated 3 wt% 'Li' doped MoO{sub 3} thin film

Abstract

The lithium (3 wt%) doped MoO{sub 3} thin film was prepared by spray deposition onto ITO substrate at 325 Degree-Sign C. The film of thickness 577 nm was irradiated with 200 MeV Ag{sup 15+} ion beams at a fluence of 5 Multiplication-Sign 10{sup 12} ions/cm{sup 2}. The XRD pattern confirmed that the pristine film is polycrystalline with orthorhombic symmetry. Upon irradiation, the film turned amorphous. The sharp Raman peak in pristine film at 993 cm{sup -1} is due to the terminal oxygen of {alpha}-MoO{sub 3} phase. Optical transparency of the film increased upon irradiation. Large red shift was observed in both direct and indirect band gaps. Electrical transport property study shows that the carrier concentration increased by one order for the irradiated film.
