E. Chingprado et al., MICRO-RAMAN STUDY OF BATIO3 THIN-FILMS PREPARED BY THE METALLOORGANICDECOMPOSITION TECHNIQUE, Journal of Raman spectroscopy, 25(3), 1994, pp. 215-219
A micro-Raman probe was used to characterize thin films of barium tita
nate synthesized by metallo-organic decomposition and rapid thermal an
nealing techniques. All films were found to be polycrystalline aggrega
tes with perovskite as the primary phase. The optimum film processing
procedure as evidenced by the micro-Raman probe was a combination of r
apid thermal annealing at 950-degrees-C in an oxygen or argon atmosphe
re. Fourier transform infrared spectra indicated that samples annealed
in a vacuum show higher carbon contamination than those receiving the
same heat treatment in an oxygen or argon atmosphere.
