Preparation of Ca2SnO4:Tb3+, R3+ phosphors (R3+ = B3+, Al3+ or Ga3+) and the dependence of their luminescence on R3+ cations
Source abstract
Abstract
Abstract Ca2SnO4:Tb3+ phosphors co-doped by R3+ cations (R3+ = B3+, Al3+, Ga3+) can be prepared by a solid-state reaction. They are fine solid solutions, which have been studied in detail by XRD, photoluminescence spectra, and decay curves. The results show that their luminescence can be effectively improved by co-doping R3+ cations and adding Al3+ cation is superior to that with other two dopants whether in fluorescence or phosphorescence. The concentration quenching effect will weaken their luminescence beyond m = 0.07 when Al3+ cation is co-doped. The distortion of host lattice and change of local crystal field symmetry around Tb3+ due to co-doping R3+ can enhance their fluorescence. The formation and increase of oxygen vacancy (V••O) predominate in improving their phosphorescence, while the single bond strength of R-O also plays an important role.
