摘要：

For the first time much more intense (4)G(5/2) -> H-6(9/2) transition than others (4)G(5/2) -> H-6(J/2) transitions of the Sm3+ doped oxides have been observed. The Sm3+-doped LaKNaTaO5 single crystals have been grown by the flux growth method. The emission and excitation spectra as well as decay profiles of the (4)G(5/2) luminescent level of the Sm3+ ion have been measured. The decay curve has been fitted by the Inokuti-Hirayama energy transfer model which revealed that electric dipole-dipole interaction is responsible for the energy transfer processes in the Sm3+:LaKNaTaO5 single crystals. The title phosphors may be potentially used as red phosphor for white light-emitting diodes.
