Though only weakly doped with Er3+ ions, centimeter-sized and good quality single crystals could be grown and analyzed. Excitation and emission spectra recorded at low temperature and crystal-field calculations agree with the existence of only one dominant Er3+ substitutional site. Anti-Stokes emission and excitation spectra as well as fluorescence decays and time-resolved emission and excited-state excitation spectra were recorded and analyzed to determine the different ways of populating the Er3+ excited levels and to provide all the necessary elements for an estimate of the laser potential of the considered material under diode laser pumping around 800 nm. %G English %L cea-00344127 %U https://cea.hal.science/cea-00344127 %~ CEA %~ CNRS %~ INSA-ROUEN %~ ICMCB %~ COMUE-NORMANDIE %~ IRAMIS-CIMAP %~ UNIROUEN %~ ENSICAEN %~ UNICAEN %~ INSA-GROUPE %~ CIMAP %~ OML-CIMAP %~ IRAMIS
