“…The peak at 3477 cm −1 corresponds to OH vibrations, while at 1027 cm −1 belongs to stretching vibrations of C─N [21]. The sharp intense peaks at 3555 cm −1 , 1526 cm −1 , 1287 cm −1 and 741 cm −1 correspond to N─H stretching, NO 2 asymmetric stretching, CH stretching and NH 2 rocking vibration respectively [22,23]. The Out of plane ring C═C bending bands observed at 2878 cm −1 , 2424 cm −1 and 2050 cm −1 vibrations are attributed to CH stretching, S─H stretching and OH ─ group vibrations respectively [24][25][26].…”

Bulk size of urea barbituric acid single crystal which have not been reported earlier was successfully grown by slow evaporation solution growth method. Single-crystal XRD brought out the lattice constant and the crystal system is observed to be monoclinic with space group P. Functional group of UBA were determined by FT-IR. Title crystal is entirely visible from 270 to 900 nm with linear optical energy gap value to be 4.50 eV. The observed HOMO-LUMO energy gap was 5.21 eV. Thermally, UBA crystal is found to be stable up to 184˚C. The Cp value of UBA increases from 1.21 to 1.58 J/gK with the temperature difference from 30 to 100˚C. UBA shows good photoconductive nature and it found to be positive and Laser Damage Threshold (LDT) value of UBA crystal is 0.97 GW/cm2. Hardness testing confirms that UBA crystal belongs to soft nature category. Dielectric properties of UBA crystal are studied as a function of frequency and temperature. Third order NLO properties of the UBA crystal were studied under CW and pulsed lasers (ns) regimes using Z-scan technique. Good Optical limiting (OL) response confirms the efficiency of UBA crystal to be used as optical limiters for protection towards short pulse lasers.

“…Urea has a reasonably high laser damage limit and large nonlinear optical constants [19]. Slow evaporation and seed rotation techniques were used to synthesize and grow the organic nonlinear optical crystal, urea p-nitrophenol, for its potential use as an optical limiter, as reported by Suresh et al [20]. Te Z-scan approach outcome reveals that the tests are suitable for studies on optical limiters due to their optical nonlinearity.…”

In silico investigation of the effects of a molecule’s framework and surroundings on its nonlinear optical (NLO) response is still an active topic of study in the fields of photonics and optoelectronics. NLO materials play a crucial role in modern photonics and optoelectronic technologies. Presented here is a comprehensive theoretical analysis of the structural, topological, and NLO features of 1-methylurea butanedioic acid (MUBA) alongside solvent effects (water, DMSO, and benzene) using the DFT method at the B3LYP(D4)/6–311++G(d,p) level. Geometric and infrared parameters were calculated and compared with experimental values. The analysis using atoms in molecules (AIM) and the independent gradient model (IGM) reveals the presence of two noncovalent intermolecular interactions: N4–H16⋯O12 and O6–H25⋯O3, which stabilize the crystal structure. The natural bond orbital (NBO) analysis reveals that the LP(1)N4 ⟶ π∗(C2-O3) interaction is the most stabilizing and is enhanced in solvent environments. NLO data show that the first (βtot) and second (γ) hyperpolarizability values of MUBA are approximately 0.6–1.1 and 8.3–17.0 times higher than those of urea. In addition, the quadratic and cubic responses of MUBA are significantly reduced and increased, respectively, in solvent environments. Based on its NLO susceptibilities, MUBA exhibits SHG, EOPE, OKE, and EFISHG properties, suggesting its potential application in the production of optoelectronic devices and optical limiting. This study enhances our understanding of the factors influencing the NLO behaviour of organic crystals, providing valuable insights for designing materials with enhanced NLO characteristics. The implications extend to industries such as telecommunications and computing, where faster data transmission rates are in high demand.

The third-order optical nonlinearities of methyl green in aqueous solution are studied by the Z-scan technique using a femtosecond laser at 800 nm. The valley shape in the open aperture measurements reveals the presence of reverse saturable absorption effect, which is ascribed to the three-photon absorption process. The closed aperture Z-scan traces demonstrate a negative sign for the nonlinear refractive coefficient, indicating the self-defocusing optical nonlinearity. Furthermore, the magnitudes of the nonlinear refractive index n 2, the three-photon absorption coefficient α 3, and the real part of the third-order nonlinear optical susceptibility Re χ (3) are determined and found to be linearly proportional to the dye concentration within the investigated range. Our results suggest that methyl green may be a hopeful candidate for applications in nonlinear optics.
