Evidence of presence of Ce traces in traseodymium doped lutetium and yttrium orthoborates and their influence on Pr3+ luminescence spectra
The luminescence of three compounds: LuBO3, with calcite and vaterite structures, and YBO3 (vaterite structure) doped with Pr3 ions has been investigated. The emission was ascribed to four spin-allowed transitions and one spin-forbidden transition from the 4f5d to the 4f2 c...

| Résumé: | The luminescence of three compounds: LuBO3, with calcite and vaterite structures, and
YBO3 (vaterite structure) doped with Pr3 ions has been investigated. The emission was
ascribed to four spin-allowed transitions and one spin-forbidden transition from the 4f5d to
the 4f2
configuration. Two additional broad emission bands with very weak intensity at 440
and 580 nm were studied. Evidence of the presence of Ce3
traces is reported and their
influence on Pr3
luminescence is discussed. |
