Micro-Raman study of the m-MoO2 to α-MoO3 transformation induced by cw-laser irradiation

►In this work, we have reported for the first time to our knowledge evidence of the monoclinic-MoO2 to α-MoO3 transition induced by a low power cw-laser. ►This material can be a good candidate for optical recording applications. ►The transition threshold, from m-MoO2 to α-MoO3 was determined by in-situ micro-Raman spectroscopy.
