Description

The Yb radiative lifetime of 923 μs has been determined by the extrapolation to the zero concentration of Yb. Quenching of the Yb luminescence is observed in the Yb3+,Ce3+:CaGd4Si3O13 (Yb,Ce:CGS) crystals due to their intrinsic defects and Ce3+ ions. The main quenching mechanism is the energy migration through Yb ions to the defects with a micro-parameter CDD (Yb-Yb) = 1.0x10-38 cm6 s-1, and the Yb3+ → Ce3+ energy transfer with a micro-parameter CDA = 5.5x10-44 cm6 s-1.
