Abstract: (4752 Views)
In this research, spectrum properties of Eu3+ doped glass and glass-ceramic with composition 64.5P2O5, 35CaF2, 0.1Eu2O3 before and after irradiation of 10MeV electron beam have been investigated. Absorption spectrum of Eu+3 doped samples were taken in the wavelength region at 200-1000nm and Excitation spectrums in wavelengths 590 and 615 nm that can be assigned to5D0→7F1and5D0→7F2transitions respectively have been monitored. It indicates that in irradiated samples have sharp peaks rather than non-irradiated samples. Emission spectrums in wavelength 392 and 463 nm have been taken, the results show local asymmetry of lanthanide will be reduced by electron-beam radiation.
Keywords: Absorption and emission spectrum, irradiation of electron beam, nano glass-ceramic, oxyflouride glass, rare earth elements
