Manganese tungstate (MnWO4) nanoparticles were synthesized at room temperature by chemical precipitation method. The effect of high energy electron beam (EB) irradiation on the optical properties of MnWO4 nanoparticles was investigated. The absorption spectra, photoluminescence intensity, and Raman bands of the irradiated samples were modified, which has been attributed to defects and particle size variation. The present investigation found that the beam irradiation is a new and efficient method to enhance the optical absorption performance and photoactivity of MnWO4 nanoparticles.
