Virgin GeGaS film is only a little bleached by the illumination with the band gap or over band gap photons while the film annealed in the argon is practically insensitive to such illumination. Illumination by UV photons leads to significant changes in the surface topology of the virgin or annealed film originated from the film oxidation, which is supported by Fourier transform infrared spectroscopy (Ge-O-Ge bridge), the Raman fearure (O3Ge-O-GeO2) and (iii) Atomic Force Microscopy (GeO2 microcrystalline particles).
