摘要

AbstractCubic garnets activated by neodymium and holmium, Li_6CaLa_2Nb_2O_12:Nd^3+,Ho^3+, were obtained by solid-state method. The main regularities of changes in the luminescence properties of Li_6C-aLa_2Nb_2O_12:Nd^3+,Ho^3+ solid solutions in the visible, near-IR, and short-wave IR ranges under 808 nm laser diode radiation are determined. The energy transfer mechanism between active centers, involving the participation of Nd^3+ ions as sensitizers for the luminescence of Ho^3+ ions, is proposed. Low phonon energy, high luminescence intensity in the range of 2.0–3.0 μm, and weak up-conversion luminescence in the region of 450–780 nm make it possible to consider the cubic lithium–lanthanum niobates Li_6CaLa_2Nb_2O_12:Nd^3+,Ho^3+ as promising phosphors of the short-wave IR range.
