摘要：
The presence of multiple Er3+ luminescent centres in calcium lithium niobium gallium garnet is investigated using selectively excited luminescence spectra of transitions S-4(3/2) -> I-4(15/2) and I-4(11/2) -> I-4(15/2) pumped in infrared (I-4(15/2) -> I-4(9/2)) at low temperature (10 K). Three luminescent centres were identified and the positions of the lowest four sublevels of their I-4(15/2) energy level could be estimated.
