“…Comparison of hydrothermally grown and CZ BSO crystals [121][122][123] indicates that the concentration of optical centers responsible for the coloration of sillenites is two orders of magnitude lower in hydrothermal BSO. Hydrothermally grown Bi 12 M x O 20 ± δ (M = Zn, B, Al, Ga, Tl, P, V) crystals were shown to contain isolated, noninteracting OH groups whose concentration (10 17 to 10 19 cm -3 ) exceeds that in CZ crystals (~10 16 cm -3 ) [140,141].…”

“…A viable alternative to the melt growth of sillenite compounds is hydrothermal crystallization [108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123]. This method has the advantage of low growth temperatures, which enables the synthesis of phases that decompose in the solid state and, hence, cannot be prepared by melt growth.…”

“…Most research effort has been concentrated on Bi 12 GeO 20 (BGO), Bi 12 SiO 20 (BSO), and Bi 12 TiO 20 (BTO) crystals. The approaches most frequently used to prepare BGO, BSO, and BTO crystals are melt growth (Czochralski (CZ), Bridgman, Stepanov, and edge-defined film-fed growth (EFG) processes) and hydrothermal crystallization [108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123]. Films of these compounds can be produced by liquid phase epitaxy (LPE), physical sputtering, chemical vapor transport, and solution growth .…”

The main processes for preparing bulk single crystals and films of photorefractive and piezoelectric Bi 12 M x O 20 ± δ (M = Group II-VIII elements) sillenite compounds are considered. Experimental data are summarized on the crystal growth of Bi 12 M x O 20 ± δ from the melt and under hydrothermal conditions, and the key morphological features of sillenites are analyzed. Various types of macroscopic growth defects in sillenite-type crystals are described, and their origin is discussed. The compositions of second-phase inclusions in undoped and doped (Group I-VIII elements) Bi 12 SiO 20 , Bi 12 GeO 20 , and Bi 12 TiO 20 single crystals are presented, and the main physicochemical properties of various Bi 12 M x O 20 ± δ crystals are summarized.
