Abstract
We have measured at room temperature the photoacoustic spectra of Cd1- xFexTe (0 < x < 0.055) around the CdTe fundamental absorption threshol d. We identified an absorption band at (1.38 +/- 0.01) eV, increasing with the Fe concentration, that we assigned to the 3E --> 3T1 transiti on within the Fe2+ (3d6) manifold. We observed also a broadening and a shift to higher energies of the CdTe absorption edge for increasing x .
