Recently, hole-doped superconducting cuprates with the T'-structure
La1.8-xEu0.2SrxCuO4 (LESCO) have attracted a lot of attention. We have
performed x-ray photoemission and absorption spectroscopy measurements on
as-grown and reduced T0-LESCO. Results show that electrons and holes were doped
by reduction annealing and Sr substitution, respectively. However, it is shown
that the system remains on the electron-doped side of the Mott insulator or
that the charge-transfer gap is collapsed in the parent compound.
