Abstract

Crystallization behavior of BaO-Ln 2O 3-TeO 2 glasses (Ln = La, Pr, Sm, Eu, Er) was examined to prepare transparent crystallized glasses consisting of lanthanide tellurite crystals (Te 4+ crystalline compounds) with low phonon energies. Transparent crystallized glasses with fluorite-type Ln 2Te 6O 15 or Ln 2Te 5O 13 nanocrystals (∼50 nm sizes) were successfully prepared for the first time. The crystallization mechanism depends strongly on the lanthanide species: surface crystallization (∼15 μm) is dominant in La 3+ and Pr 3+ containing glasses, but homogeneous nucleation occurs easily in Sm 3+, Eu 3+ and Er 3+ containing glasses, giving transparent bulk crystallized glasses. These transparent nano-crystallized glasses are applicable to fabrication of optical amplified waveguides or Bragg grating fibers.
