摘要: The emission and excitation properties of a SrB4O7:1% Pr3+ powder sample Sr0.7La0.3Al11.7Mg0.3O19:3.5% single crystal were investigated using x-ray synchrotron radiation. 4f5d states in these host lattices are at higher energy than the 4f2[1S0] state. In hexa-aluminate this results successive two photons. 1S0→1I6 is followed by from 3P0 quantum efficiency total 25%. tetra-borate quenched multiphonon relaxation to 1D2 state which only weak observed. as tetra-borate, lattice does not result efficient 1S0 transferred preferentially lower-energy 3PJ 1I6 states, resulting only.
