Abstract: A study of intrinsic luminescent properties of two polymorphic modifications of gadolinium molybdate was conducted using synchrotron radiation at low temperature. Excitation spectra in the UV- and VUV-ranges (E exc = 3.7-21 eV) were measured. Energy transfer from Gd3+ to (MoO4)2- centers was observed. Change of crystal structure influenced luminescent properties, with less symmetric phase having higher quenching temperature and lower emission. After irradiation of the crystals with fast electrons, the creation of a new luminescent center was registered with a separate excitation and emission bands. Temperature dependences of luminescence yield of all bands were measured. © 2013 Elsevier Ltd. All rights reserved.
