The oxygen content of YBa2Cu3O7-delta epitaxially grown thin films can be quantitatively evaluated from variations of the scattering efficiencies of lattice vibrations as measured by near-infrared excited Raman spectrometry. An empirical procedure allows an accurate (< +/- 0.03 delta for delta less than or equal to 0.42), absolute and non-destructive measurement to be made to a spatial resolution in the micrometer range under ambient conditions, without reference measurements or special sample preparation and on a short time scale. The method is independent of kinetic ordering effects and laser-induced photoconductivity.
