Radiative and non-radiative transitions of excited Ti(3+) cations in sapphire
We have measured the fluorescence quantum efficiency in Ti(3+):sapphire single crystals between 150 K and 550 K. Using literature-given effective fluorescence lifetime temperature dependence, we show that the zero temperature radiative lifetime is (4.44 ± 0.04) μs, compared to the 3.85 μs of the flu...
