The local environment about oxygen atoms in Pr[sub [ital x]]Y[sub 1[minus][ital x]]Ba[sub 2]Cu[sub 3]O[sub 7] films obtained by laser ablation has been investigated by means of the x-ray absorption fine structure (XAFS) spectroscopy at the O K-edge. It has been found that the Pr atoms do not subsitute for the Cu atoms nor form interstitial defects in the CuO[sub 2] planes and that the presence of Pr dopant does not disturb the local environment of oxygen.
