In this paper nanoparticles, La0.6Sr0.4MnO3 via microwave radiation method is provided. The structural, magnetic, optical and photocatalyst properties by X-ray diffraction (XRD), Transmission electron microscope(TEM), Fourier transform infrared spectroscopy (FTIR), Vibrational sample magnetometer (VSM) and UV–Vis spectroscopy (UV-Vis) were studied. Lattice constants, cell volume, and space group as well as length and angle of bonds obtained by XRD analysis. Using the UV-Visible spectrometer, an examination of the particle absorption spectrum confirmed the existence of a band gap like semiconductors at about 1.8 eV. The degradation of nanoparticles on methyl orange dye under visible light evaluated about 83% in 50 minutes.
