Superconducting Tl-1223 and Tl-2223 films have been prepared in a two steps process : deposition of Ba:Ca:Cu = 2:2:3 precursor by spray pyrolysis and ex-situ thallination. Pure textured Tl-1223 films with good superconducting properties (Tc = 113K and Jc = 0.7 MA/cm2 at 77K, 0T) have been obtained. Almost pure Tl-2223 films have been obtained when precursor films have been thallinated with fluorinated sources.
