“…Inorganic phosphate materials have received considerable attention due to their rich structures and excellent physicochemical properties, as well as possessing broad applications in the fields of nonlinear optics, ferroelectricity, luminescence, energy technologies, and catalysts [ 1 , 2 , 3 , 4 , 5 ]. For instance, KTiOPO 4 (KTP) and KH 2 PO 4 (KDP) crystals have been used for solid-state lasers as important nonlinear optical materials, and olivine-type LiFePO 4 is an outstanding cathode material for rechargeable Lithium batteries with high capacity [ 6 , 7 , 8 ]. In the structure of phosphate materials, one P atom is generally coordinated with four O atoms to shape into the [PO 4 ] tetrahedra.…”

Phosphate crystals attract much attention on account of their rich crystal structures and excellent physical and chemical properties. Herein, Rb3Ti3P5O20 single crystals were grown by the high temperature solution method using Rb2CO3 and NH4H2PO4 as the fluxes. This crystal, with non-centrosymmetric Pca21 space group, presents a three-dimensional framework structure composed of [TiO6] octahedron, [PO4] tetrahedra, and [P2O7] dimers. The electronic structure was measured via X-ray photoelectron spectroscopy. The measurements found that Rb3Ti3P5O20 has stronger Ti–O ionic bonding properties and weaker P–O covalent bonding properties compared to RbTiOPO4. Optical measurements indicated that Rb3Ti3P5O20 has a 3.54 eV band gap and a wide transmission range (0.33–4.5 μm). Theoretical calculations showed that Rb3Ti3P5O20 crystals have a moderate birefringence of 0.079 at 1064 nm. In addition, the relationship of the structure–property was studied using first-principles method. The results demonstrated that TiO6 octahedron played a significant role for the optical properties.

“…Nonlinear organic and semiorganic single crystals are widely used in different scientific and technological applications due to their efficacy in generating second-order harmonics for various lasers source. [1][2][3][4] Recent decades have shown that such single crystals are capable of producing second harmonics due to their non-centrosymmetric nature and are also potential candidates for the generation and detection of terahertz (THz) waves, 5 which are considered to represent a bridge between optical waves, i.e., infrared, and microwaves in the electromagnetic (EM) spectrum with frequencies generally in the range from 100 GHz to 10 THz. Radiation in the terahertz region is very useful for producing images in various fields such as medical, defense, and security.…”

Organic nonlinear-optical single-crystal methyl p-hydroxybenzoate (MPHB) is one of the potential candidates for use in terahertz applications. The focus of this work is to study the response of MPHB single crystal in the terahertz region of the electromagnetic spectrum using time-domain terahertz spectroscopy (THz-TDS). Single-crystal MPHB was grown by the conventional slow evaporation solution growth technique (SEST). The structural confirmation of the title compound was assessed by powder x-ray diffraction (PXRD) analysis. The optical bandgap of ingot crystal was calculated using Tauc's equation based on ultraviolet-visible (UV-Vis) spectroscopy. The photoluminescence emission spectrum revealed a major emission in the blue region corresponding to 457 nm. The dominant color emission for the title compound was assessed by converting the major emission peak to a Commission Internationale de l'Éclairage (CIE) chromaticity diagram, which further confirmed the emission of blue light from the crystal. The dynamics of the photon emission and its decay time for the title compound were studied by time-resolved photoluminescence (TRPL). THz-TDS was performed in the range from 0.2 THz to 3.0 THz on the title single crystal to observe its optical absorption behavior in the THz energy range. The variation of the absorption coefficient at terahertz frequencies is also presented herein.

This paper reviews the progress in developing the LaxYySc4-x-y(BO3)4-LYSB and Yb-doped LaxYySc4-x-y(BO3)4-LYSB:Yb huntite-type crystals grown by the Czochralski method as new candidates for the next generation of nonlinear optical (NLO) and/or laser crystals. Considering the incongruent melting of these crystals, the initial compositions of the melt and the pulling and rotation rates were optimized. Additionally, a special thermal setup was engineered to grow LYSB-type crystals by the Czochralski crystal growth method. The chemical compositions of the LYSB and LYSB:Yb grown crystals were found to be La0.78Y0.32Sc2.90(BO3)4 and La0.78Y0.32Yb0.04Sc2.86(BO3)4, respectively. Therefore, for the LYSB:Yb crystal, the doping concentration of Yb3+ ions was considered to be 4 at.% with respect to the nonstoichiometric (La1-xYx)1.25Sc2.75(BO3)4 undoped compounds, i.e., LYSB:Yb (4 at.%). In terms of NLO properties, the obtained results demonstrate that LYSB and LYSB:Yb (4 at.%) crystals possess remarkable properties specific to huntite-type crystals. The main advantage of these crystals consists in the fact that they may be obtained with large dimensions and excellent optical quality by the Czochralski method, which recommends them as a new class of highly efficient crystals for different NLO applications, including second harmonic generation (SHG) of high-power or high-energy laser beams. The laser performances of the LYSB:Yb (4 at.%) crystal prove its favorable intrinsic properties to generate laser emissions in the 1 µm range with high efficiency. The efficient laser emission at ~1028 nm together with good NLO characteristics to convert its own emission into emission at ~514 nm via SHG make the LYSB:Yb (4 at.%) crystal a very promising active medium to be used in self-frequency doubling configuration.
