Notes:
3 O7 crystal have been recorded at room temperature and at approximately 8 K. Room-temperature luminescence lifetimes of 1D2, 1G4, 3H4, and 3F4 states have been measured for Tm concentration ranging from [%at.]0.5 to [%at.]9. Based upon these data the crystal field splitting of luminescent states has been derived and radiative transitions rates have been evaluated. Strong self-quenching of luminescence originating in the 1G4 and 3H4 states has been found in this activator–host combination. Peak emission cross section of the potential laser transition at 1800 nm was determined to be 3.9×10-21 cm2 and the gain coefficient versus wavelength was estimated and discussed.
