| Undoped and Eu3+-doped disodium zinc diphosphate Na2ZnP2O7 (NZPO) single crystals are grown by the Czochralski method. X-ray diffraction, Fourier transform: infrared and Raman techniques were used to check the crystallographic structure. Excitation and emission spectra were measured at room temperature and studied. The Eu3+ ions occupy a non-centrosymmetric site with different coordination number. Very efficient energy transfer from O-Eu3+ band state to Eu3+ excited energy levels is highlighted. |
