We present a Raman scattering study of the B₂O₃ as a function of temperature. Measurements have been done from liquid helium up to the supercooled liquid state. We found that the BP shift could be completely ascribed to the temperature elastic medium transformation and we do not need the introduction of other mechanisms. Furthermore we shown also in this system that the boson peak spectral shape is invariant.
