Abstract

We are reporting the positron behaviour in transition metal chloride FeCl3 doped PVA/PVP (50:50) blend. Pure and FeCl3 doped blend films were prepared using solution casting method and studied using X-ray Diffraction (XRD) and Positron Annihilation Lifetime Spectroscopy (PALS). XRD studies show that the doping increases the amorphous nature of the blend and the PALS studies reveal that the o-Ps lifetime (τ₃) and intensity (I₃) decreases with increase in FeCl₃ doping level. This is due to chemical quenching and inhibition process of Ps due to doping concentration, which are discussed in the text.
