Bi12GeO20 single crystals were grown by the Czochralski technique. Suitable polishing and etching solutions were determined. Reflection spectra were recorded in the wave numbers range 20-5000 cm-1, and compared with the spectra of Bi12SiO20 single crystals to study the position of the phonon modes. The optical constants of the Bi12GeO20 single crystals were obtained using Kramers-Kronig analysis. The obtained results are dicussed and compared with published data.
