“…Electron paramagnetic resonance (EPR) measurements show that transition metal impurities often go into the tetrahedrally coordinated Ge site [17][18][19][20]. In this article, we present an investigation of the PL response of Bi 12 GeO 20 doped with the 4d ion Mo.…”

Photoluminescence (PL) of Bi 12 GeO 20 and Mo doped Bi 12 GeO 20 (Mo: Bi 12 GeO 20 ) crystals in visible and near-infrared (NIR) spectral regions were studied. X-ray diffraction analysis, absorption and Raman scattering spectra of these crystals were also measured. Pure Bi 12 GeO 20 after annealing in N 2 atmosphere at 450 ºC and 550 °C show predominant emissions at about 745 and 1250 nm bands, while the emission peaks of Mo:Bi 12 GeO 20 crystals untreated or after annealing in Ar at 300 °C are at around 538 and 1165 nm. The results suggest that annealing induces intrinsic luminescence of Bi in pure Bi 12 GeO 20 at room temperature and Mo influences the luminescence centers of Bi 12 GeO 20.

“…[16][17][18][19] In addition, they are used in optoelectronic devices because of their photorefractive properties, and their high electro-optical coefficients make them applicable in the field of holographic interferometry. 20 On the other hand, perovskite-like Bi 4 Ti 3 O 12 has been used as a promising material for nonvolatile ferroelectric random access memories (FRAMs) because of its excellent fatigue resistance during repeated polarization reversals with an electric field. 21 The synthesis of Bi 12 TiO 20 and Bi 4 Ti 3 O 12 is extensively explored using many methods, [22][23][24][25] and several morphologies, such as nanowires, 26 nanotubes, 27 and hierarchical assemblies, have been reported as photoactive materials.…”

Density functional theory calculation was conducted to determine the optoelectronic properties of bismuth titanate sillenite (Bi12TiO20) and perovskite-like (Bi4Ti3O12) structures. The lattice parameters were experimentally obtained from Rietveld analysis. The density functional perturbation theory approach was used with the standard Perdew–Burke–Ernzerhof functional and screened Coulomb hybrid Heyd–Scuseria–Ernzerhof functional to investigate the electronic structure and absorption coefficient. Both compounds have good carrier transport properties, low effective hole and electron masses, high dielectric constant, and low exciton binding energy.

“…The piezoelectric, acoustic, optical, chiroptic, photorefractive, and other properties of sillenite-type crystals have been the subject of many reviews, handbooks, and monographs (see, e.g., [1][2][3][4][5][6][7][142][143][144]). Most published data refer to the well-known compounds BSO, BGO, and BTO.…”

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.
