Kopsavilkums

Single crystals of three oxide compounds containing stoichiometric Nd, doped with Yb³⁺ ions, namely K₅Nd(MoO₄)₄ (KNM), RbNd(WO₄)₂ (RNW), and NdAl₃(BO₃)₄ (NAB) were grown from melts using Czochralski method or top seeded solution growth technique. Nd³⁺ fluorescence characteristics were measured in dependence of Yb³⁺ content and temperature. It was established that increasing Yb³⁺ content results in a decrease of the Nd³⁺ lifetime. However, the corresponding decay times values were quite different and varied from 9.5 μs for NAB up to 60 μs for KNM and 3.3 μs in RNW. Judd-Ofelt theory was applied to estimate the intrinsic lifetime of the ⁴F_3/2 emitting level of Nd³⁺ for all three crystals. The calculated lifetime values are much higher than the measured values. This effect is attributed to the strong concentration quenching of the Nd³⁺ ions due to their high concentration in all three crystals. The possible mechanisms of the observed dependences are given.
