The high optical quality glasses with Li<sub>2</sub>B<sub>4</sub>O<sub>7</sub>:Eu, CaB<sub>4</sub>O<sub>7</sub>:Eu, and LiCaBO<sub>3</sub>:Eu compositions containing 0.5 and 1.0 mol. % Eu<sub>2</sub>O<sub>3</sub> have been obtained by standard glass technology. Using electron paramagnetic resonance (EPR) and optical spectroscopy it was shown that the Eu(More)
We review the pyroelectric properties and electronic structure of Li 2 B 4 O 7 (110) and Li 2 B 4 O 7 (100) surfaces. There is evidence for a pyroelectric current along the [110] direction of stoichiometric Li 2 B 4 O 7 so that the pyroelectric coefficient is nonzero but roughly 10 3 smaller than along the [001] direction of spontaneous polarization. Abrupt(More)

In the current work we report on the synthesis of LiKB(4)O(7), Li(2)B(6)O(10), and LiCsB(6)O(10) borate glasses. The results for their piezo-optic, acousto-optic, acoustic, elastic, refractive, optical transmission, and optical resistance properties are also presented. It is shown that some of these glasses represent efficient acousto-optic materials that(More)
