Controlling the structural organization and crystallinity of functional oxides is key to enhancing
their performance in technological applications. In this work, we report a strong enhancement of
the structural organization and crystallinity of Bi2WO6 samples synthetized by a microwave-assisted
hydrothermal method after exposing them to femtosecond laser irradiation. X-ray difraction, UVvis and Raman spectroscopies, photoluminescence emissions, energy dispersive spectroscopy, feld
emission scanning electron microscopy, and transmission electron microscopy were employed to
characterize the as-synthetized samples. To complement and rationalize the experimental results, frstprinciples calculations were employed to study the efects of femtosecond laser irradiation. Structural
and electronic efects induced by femtosecond laser irradiation enhance the long-range crystallinity
while decreasing the free carrier density, as it takes place in the amorphous and liquid states. These
efects can be considered a clear cut case of surface-enhanced Raman scattering. [-]
