A structurally ordered rare earth two‐dimensional nano‐thin film using polyethylene terephthalate (PET) as carrier was obtained using the homogeneous precipitation method. Films with different sizes and morphologies were prepared by adjusting reaction temperature, reaction time and concentration of reactant. Microstructures of the films were obtained by scanning electron microscopy and energy dispersive spectrometry, and the results showed that the sample revealed the optimal micro‐morphology when it was prepared at 85°C for 24 h with the concentration of Y(NO 3 ) 3 . 6H 2 O, H 2 NCONH 2 and C 12 H 25 SO 4 Na fixed at 0.01 M, 0.04 M and 7 g/l, respectively. Moreover, uniform, dense and ordered films were successfully prepared over a large area at the gas–liquid surface using PET as carrier.
