Influence of temperature on luminescence of terbium ions in LiNbO{sub 3}
Single crystals of LiNbO{sub 3} doped with terbium were grown by the Czochralski method and their optical properties were examined. It has been found that, in contrast to isostructural LiTaO{sub 3}:Tb, the terbium ions in LiNbO{sub 3} exhibit intense luminescence at low temperatures only, up to about 150 K. At this temperature, a luminescence quenching mechanism with activation energy of 0.22 eV is switched on. As a consequence, the luminescence of LiNbO{sub 3}:Tb is reduced to a negligible level at room temperature. {copyright} 2001 American Institute of Physics.
