Using the techniques of in-beamγ—ray spectroscopy,the high-spin states of the neutron-rich nuclei sb, sn,and In were studied via the Cd（Li,5n）sb,Cd（Li,3n）sb,Cd（Li,4n1p）sn and Cd（Li,α3n）In fusion-evaporation *** DCO ratios andγ—γcoincidences were *** a result of these experiments the level schemes of sb,sn,and In were significantly extended. Excited states of these neutron-rich nuclei were discussed within the framework of the particle-rotor model （PRM） and the triaxial relativistic mean-field（RMF） approaches.

We investigated the emission properties of Eu3+-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3+emission by codoping of Bi3+and Li+.Eu3+singly doped,Eu3+and Bi3+doubly doped,and Eu3+,Bi3+,and Li+triply doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3+in the singly doped samples are significantly improved by the codoping of Bi3+,mainly due to the energy transfer from Bi3+to Eu3+.The additional codoping of Li+is found to increase the Eu3+emission *** improvement might be attributed to the increase in the photoluminescent quantum yield originating from larger grain sizes and better crystallinity.A detailed analysis of the X-ray diffraction pattern and the asymmetric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3+in GdNbO4does not change significantly with the codoping of Bi3+and Li+.Our results indicate that Li+doping is a promising way to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.
