Growth, characterization and theoretical analysis of α-SrGeO3 as a candidate mid-IR stimulated Raman scattering crystal†
The α-BaGeO3 crystal is a potential stimulated Raman scattering (SRS) medium for use in generating lasers at wavelengths in the range of 2.1–2.4 μm. However, the growth of a large-sized and high-quality α-BaGeO3 crystal is still challenging. Here, we turn the attention to its analogue, α-SrGeO3. The α-SrGeO3 crystal was grown by the high-temperature solution method under conditions similar to those for growth of α-BaGeO3. The grown α-SrGeO3 single crystals have larger sizes (approximately 8 × 12 × 10 mm3) and higher quality than α-BaGeO3. A strong Raman peak at 813 cm−1 and a wide transparent window from 0.22 to 5.78 μm indicate that the α-SrGeO3 crystal is a promising SRS crystal working in the 2.1–2.4 μm wavelength range. From density functional theory (DFT) computations, the strongest Raman peak, the ultraviolet cut-off edge and the infrared cut-off edge of α-SrGeO3 are all related to the [Ge3O9]6− ring, the basic building unit in both α-SrGeO3 and α-BaGeO3, which suggests that the [Ge3O9]6− ring is a valuable structural group for developing new mid-IR SRS crystals.
