Synthesis, structure and non-linear optical properties of l-argininium perrhenate crystal

Abstract

A new hybrid organic-inorganic non-linear optical crystalline material, L-argininium perrhenate has been synthesized. The crystal belongs to P2 1 2 1 2 1 space group, has a good optical quality and high transmission in the visible and near infra-red spectral regions. L-argininium perrhenate has high birefringence and is more than four times as efficient as KDP in second harmonic generation, making it a potentially attractive material for non-linear optical applications.

Series of SHG Materials Based on Lanthanide Borate–Acetate Mixed Anion Compounds

“…To accurately reveal which electronic states contribute to the SHG effect, we calculate the SHG density, which can provide an intuitive orbital image for the SHG contributions and had successfully interpreted the SHG effects origins for our previously reported crystals. 11,33 The SHG density graphs of d 11 in VB and CB for compound 4 are displayed in Figure 5 The results indicate that in the compound, except for the common borates groups, CH 3 COO − groups also play an important part in SHG process because of its partly planar and delocalized π bonds. In addition, La 3+ ions make contribution to SHG responses which can not be ignored.…”

“…The acetate anions are grafted on the walls of 1D tunnels of the above La 4 B 12 16-MRs whereas the lattice waters are resided in the 1D tunnels (Figure 1e). The acetate anion containing C(1), C(2), O (11) and O( 12) is tetradentate and it forms a bidentate chelation with a La(2) atom and also bridges with two other La atoms. The other acetate anion adopts a bidentate bridging coordination mode (SI Figure S3a).…”

Synthesis, growth, structure and nonlinear optical properties of a semiorganic 2-carboxy pyridinium dihydrogen phosphate single crystal

“…In addition to these properties, the absence of center of symmetry is an essential requirement for second order NLO applications while such a constraint is not applicable for third order NLO applications [5,6]. Even though both inorganic and organic materials have been examined for optical non-linearities, the former take precedence over the latter, as they can be easily constructed with extended electron cloud delocalization [7,8]. However, organic compounds suffer from poor thermal and chemical stability.…”

Bulk growth and physical properties of diguanidinium phosphate monohydrate (G2HP) as a multi-functional crystal

“…[9][10][11][12][13] The salts of protonated amino acids have become an interesting class of hydrogen bonded compounds following the discovery of the outstanding nonlinear optical (NLO) properties of L-arginine phosphate monohydrate (LAP) by our group. [14][15][16][17][18][19][20][21] Besides high NLO coefficients, short ultraviolet (UV) transparency cutoff and low level of hygroscopicity, the most attractive feature of this material is the high laser-induced damage threshold with a value of 63 GW cm −2 (1 ns pulses at 1053 nm). 22 Its deuterated analog (DLAP) exhibits an even higher damage threshold.…”
