“…6 shows the absorption spectrum recorded for a single crystal of MEAPM. There is no appreciable absorption in the entire visible range, as in the case of other NLO crystals (Rodrigues et al 2003;Uma and Rajendran 2016). The cutoff wavelength of MEAPM is 370 nm and MEAPM is transparent in the range of 370-1080 nm.…”

A novel compound, 2-(morpholino)ethylammonium picrate monohydrate (MEAPM), was synthesized using the equimolar ratio of 4-(2- aminoethyl)morpholine and picric acid. . With the slow evaporation solution growth technique, single crystals of the synthesized compound were grown. A single crystal X-ray diffraction study revealed that MEAPM crystallizes in a triclinic system with space group P. The functional groups of the title compound were confirmed by FTIR analysis. A UV-Vis-NIR optical study indicated a cut-off wavelength of 370 nm. The UV-Vis-NIR spectrum was also used to calculate the optical parameters, such as the linear absorption coefficient, linear refractive index, and extinction coefficient. The two-photon coefficient absorption coefficient and third-order optical nonlinearity of the grown crystal were investigated using the Z-scan technique. The order susceptibility is found to be 2.96x10-11 esu. A dielectric study on MEAPM revealed a dielectric constant and dielectric loss at higher frequencies. The various hardness parameters were calculated via a Vickers hardness study. The work-handing coefficient is found to be 5.2. The thermal stability of the sample was investigated by TG-DTG analysis.

“…Currently, NLO crystals play a key role in view of the growing demand for their potential application in everyday life such as laser and light diversification, interactions with materials, information technology, and so on ( Uma and Rajendran, 2016 ). Materials used for the above application must be of high transparency, low dielectric loss, and high efficiency of SHG ( Martin Britto Dhas and Natarajan, 2007 ).…”

Highly translucent nonlinear single crystals of L-Threoninum Sodium Bromide (LTSB) has been grown because of their rising need for everyday life and the XRD studies (PXRD and SXRD) solemnly affirmed the crystallinity and non-centrosymmetric space group of LTSB materials. The bonding nature and diverse functional groups in LTSB were demonstrated by FTIR analysis when they absorb infrared radiation. The optical behavior of LTSB crystals was explored through UV–Vis spectroscopy, which shows optical parameters depend on photon energy with band gap E g = 5.7 eV which was suitable for optoelectronic devices. The electrical properties of LTSB crystals were measured by using dielectric measurement. The solid state parameters of LTSB crystal were calculated. An antibacterial activity developed by LTSB crystals against different pathogenic bacteria were examined using the Agar disk diffusion process. The antibacterial inhibitory activity of LTSB crystal revealed that it can be used to treat a variety of bacterial infections.

“…Glutamic acid is a monoamino dicarboxylic α-aminoacid and a significant constituent of proteins such as myosin, insulin and edestin. It was shown to be phase matchable for optical second harmonic generation of 1.06 µm and has nonlinear optical co-efficient [12][13]. From the literature, it is inferred that L-glutamic acid has been proved to have improved NLO efficiency upon the reaction with inorganic hydrochloric acid [14] and hydrobromic acid.…”

Glutamic acid lithium sulphate monohydrate crystal is a new semiorganic nonlinear optical material. It was grown from a mixture of aqueous solution of glutamic acid and lithium sulphate monohydrate by slow evaporation technique at room temperature. The powder XRD analysis was carried out to identify the structural parameters of the grown crystals. The presence of functional groups of both reactants was qualitatively analyzed by means of Fourier transform infrared (FT-IR) spectrometer study. In UV-vis study, the existence of wide transparency window and band gap was investigated for optoelectronic device applications. In Kurtz-Perry powder technique, the second harmonic generation (SHG) efficiency of GLSMH crystal is found to be 1.933 times greater than that of KDP crystal.
