A series of Ba5Si8O(21):0.02Eu^2+,0.09RE^3+ persistent phosphors were synthesized by the solid-state reaction method.The measurement results of photoluminescence(PL),phosphorescence and thermoluminescence(TL)...
By using metal nitrates as starting materials and citric acid as a complexing agent, Y2Si207:Re3+ (Re=Eu, Tb) phosphors were prepared by a sol-gel method. X-ray diffraction was employed to characterize the resulti...

The ab initio self-consistent DV-Xa (discrete variational Xa) method was used in its relativistic and spin-polarized model to investigate the ground-state electronic structttres of the crystal YPO4 and YPO4:RE^3+ ...
We investigate the luminescence properties of Bi^3+ and RE^3+ (RE = Tb or Eu) in a Y3Ga5O12 (YGG) host system. The additional doping of Bi^3+ can enhance the luminescence of Th^3+ or Eu^3+ in this host. Energ...

Degraded chitosan, with highly water-solubility, was obtained by the oxidation of chitosan with H2O2, and then reacted with furrural. The final product coordinated with the rare earth ions (RE^3+ = Sm^3+, Eu^3+),...
