What is Deposition of Sm2O3 doped CeO2 thin films from Ce(DPM)4 and Sm(DPM)3 (DPM=2,2,6,6-tetramethyl-3,5-heptanedionato) by aerosol-assisted metal–organic chemical vapor deposition about?

Samarium-doped ceria (SDC) thin films were prepared from Sm(DPM) 3 (DPM = 2,2,6,6-tetramethyl-3,5-heptanedionato) and Ce(DPM) 4 using the aerosol-assisted metal -organic chemical vapor deposition method. a-Al 2 O 3 and NiO-YSZ (YSZ = Y 2 O 3 -stabilized ZrO 2 ) disks were chosen as substrates in order to investigate the difference in the growth process on the two substrates. Single cubic structure could be obtained on either a-Al 2 O 3 or NiO-YSZ substrates at deposition temperatures above 450 -C; the similar structure between YSZ and SDC results in matching growth compared with the deposition on a-Al 2 O 3 substrate. A typical columnar structure could be obtained at 650 -C on a-Al 2 O 3 substrate and a more uniform surface was produced on NiO-YSZ substrate at 500 -C. The composition of SDC film deposited at 450 -C is close to that of precursor solution (Sm : Ce = 1 : 4), higher or lower deposition temperature will both lead to sharp deviation from this elemental ratio. The different thermal properties of Sm(DPM) 3 and Ce(DPM) 4 may be the key reason for the variation in composition with the increase of deposition temperature.
