Optical quality single crystals and epitaxial films of Bi24B2O39 compound c
rystallized in sillenite-type structure have been fabricated by TSSG and li
quid-phase epitaxy methods, respectively. A deviation of power rotation vs.
wavelengths in visible is recorded. The important characteristics, such as
: absorption, circular dichroism, photoinduced absorption, photoconductivit
y and dark conductivity are studied. Comparison of these characteristics is
done for different sillenites. (C) 1999 Elsevier Science B.V. All rights r
