Pressure effect on luminescence dynamics in Pr3+-doped LiNbO3 and LiTaO3 crystals
No full textabstractEN: The {}^{1}\mathrm {D}_{2} \to ~{}^{3}\mathrm {H}_{4} luminescence kinetics of LiNbO3:Pr3+ and LiTaO3:Pr3+ have been measured under high hydrostatic pressure applied in a diamond anvil cell for pressures up to 200 kbar. The luminescence decays have been analysed using the continuous function decay times distribution. Two mechanisms that accelerate the emission decays with increasing pressure have been proposed: the non-radiative depopulation of the 1D2 state through the Pr3+ trapped exciton, dominating in LiNbO3:Pr3+ and pressure-induced increase of the {}^{1}\mathrm {D_{2} \to ~{}^{3}H_{4}} transition probability, dominating in LiTaO3:Pr3+.score: 30collation: 117-12
