Fluorescence properties of Eu 3+ :Y 2SiO 5 have been investigated. Transitions between 5D and 7Fwere were studied with transmission spectra, fluorescence spectra, photoluminescence excitation ( or absorption ) spectra and site selective fluorescence spectra. The X ray powder diffraction pattern of Eu 3+ :Y 2SiO 5 shows that the crystal belong to monoclinic, and lattice’s constants a, b, c and β are obtained by a simulation with the measured diffraction angles.
