Popis: |
Manganese(V)-doped crystals of Ba5(PO4)3Cl (apatite structure) and Ca2VO4Cl (spodiosite structure) exhibit highly resolved photoluminescence in the near-infrared. It is assigned to intraconfigurational 1Ea3A2 (Td notation) transitions, and the vibrational sideband structure is interpreted in terms of bending and stretching vibrations of the (MnO4)3− entity. In lightly doped samples of the apatite compound, both the intensity and the lifetime of the luminescence (τ10 K=0.41 ms) drops by an order of magnitude between 10 K and room temperature. |
