Characterization of BaF2 Thin Film Deposited by Thermionic Vacuum Arc

In this study, glass and polyethylene terephthalate (PET) sample were coated with Barium Fluoride (BaF2) as a mono layer using Thermionic Vacuum Arc (TVA) technique for the first time. The morphologies of the deposited samples were investigated by using atomic force microscopy (AFM). A stoichiometric value of coated surface was determined by energy dispersive X-ray spectrophotometer (EDS). Transmittances, reflectance, thickness and refractive indices of coated samples with BaF2 were measured by Uv-vis spectrophotometer and interferometer to characterize their optical properties. The films with high transparency and low reflections values were produced. Refractive indices values are very close to each other for glass and PET substrates.
