For the first time much more intense ⁴G_5/2 → ⁶H_9/2 transition than others ⁴G_5/2→⁶H_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 ⁴G_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.
