Effect of Electron Beam Irradiation on Optical Properties of Manganese Tungstate Nanoparticles

Effect of Electron Beam Irradiation on Optical Properties of Manganese Tungstate Nanoparticles

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...

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.http://dx.doi.org/10.1155/2013/580308
