Structure effect on the absorption and circular dichroism spectra of Sm14B6Ge2O34 crystals

The spectroscopic and chiroptical properties of rare-earth-rich borate germanate crystals of composition Sm14B6Ge2O34 have been studied for the first time. The absorption and circular dichroism spectra of the crystals have been measured. For some of the f-f transitions involved, we have calculated the dipole strength and optical rotatory power.
