The phase changes of MnO nanoparticles under laser-induced heating have been studied. Previous confirmation of the existence of MnO phase was based on the X-ray diffraction measurements. Here, we report the experimental spectra of nonresonant Raman scattering in the range between 100 and 1,600cm(-1), for a sample irradiated with 8 different laser powers. The laser-induced heating has produced change in existing phases in sample, destruction of MnO phase, and creation of MnO2, Mn3O4, and MnOOH phases along with formation of Mn2+ on the sample surface. These phase changes have been confirmed by X-ray diffraction and atomic force microscopy measurements.
