“…The second endothermic peak at 267ºC indicates the major decomposition of the material. The sharpness of endothermic peak shows a good degree of crystallinity of the crystal [21,22]. Hence, we conclude that MLHHF crystal is suitable for any application upto 167ºC.…”

A new magnesium (Mg 2+) doped L-Histidine Hydrofluoride (MLHHF) semiorganic nonlinear optical crystal was synthesized and grown by isothermal slow evaporation solution growth technique. The grown crystals have been characterized by single crystal X-ray diffraction and powder X-ray diffraction analyzes. The presence of functional groups in the MLHHF crystal was confirmed by vibrational spectroscopic analysis. EDAX analysis confirms the incorporation of metal ion into the crystal lattice of the title compound. The lower cuf-off wavelength of MLHHF was found to be 225 nm by UV-Vis-NIR spectral studies. The nonlinear optical property of the grown crystal was affirmed by Kurtz and Perry powder SHG technique using Nd:YAG laser. Thermal properties of the MLHHF crystal were investigated using thermogravimetric (TG) and differential thermal analyses (DTA). The fluorescence spectrum of MLHHF crystal was recorded to understand the luminescence properties. The dielectric constant and dielectric loss have been measured for different frequencies and at different temperatures. The results of all studies have been discussed in detail.

“…This indicates that MSLO crystal is an insulating material. The purpose of doing UV-Vis spectral study is to find the transmittance, absorption coefficient, optical band gap, extinction coefficient, optical conductivity, complex dielectric constant and linear refractive index and suitability crystal for nonlinear optical (NLO) applications [15].…”

Magnesium Sulfate-doped L-Leucinium oxalate (MSLO) single crystal was grown using slow evaporation method. Structure of the crystal was determined by single-crystal X-Ray Diffraction (XRD). Lattice parameters of MSLO crystal were determined. Optical transmittance study was done to find various linear optical parameters like band gap, reflectance, refractive index, absorption coefficient, extinction coefficient, optical conductivity. Vickers Micro hardness study was carried out to find mechanical properties such as hardness, work hardening coefficient, brittleness index and fracture toughness of the grown MSLO crystal. Kurtz-Perry powder technique with Nd: YAG laser was applied to study the second harmonic generation (SHG) competency. By using Z-scan technique, third-order NLO efficiency of MSLO crystal was calculated. LDT study was also done for MSLO crystal. It is observed that magnesium sulfate-doped L-leucinium oxalate (MSLO) crystal has the superior properties compared to that of undoped L-leucinium oxalate crystal. EDS studies were conducted for MSLO crystal to check the elements present in the crystal.

“…Solutions of this dye are commonly used in biology as a staining fluorescent dye for optical microscopy and in optical applications to provide laser gain media. Dyeing of crystals is a practice developed particularly for quantum optics applications, because of the very significant increase in surface area achieved in growing crystals [8]. The grown crystals were subjected to various characterizations such as single crystal XRD, FTIR, UV, NLO, dielectric studies, thermal and mechanical analysis and the results are discussed in detail.…”

Organic Non-linear optical single crystals with the second harmonic generation values are useful in optical communication and signal processing in integrated optics. Rhodamine is a dye, an organic molecule well-studied in laser physics and nonlinear optics for its fluorescent properties. In the present work, a new organic rhodamine dye doped Butylated hydroxy toluene (DBHT) single crystals were grown by slow evaporation technique. The lattice parameters of the grown crystals are found from single crystal XRD analysis. The FT-IR analysis confirms the presence of various functional groups available in DBHT. The dielectric analysis can be used to find the electrical properties of DBHT single crystal as a function of temperature and frequency. The optical studies carried out reveal that the DBHT crystals exhibit good optical quality and possible NLO applications. The thermal and mechanical stability of the crystal is studied by TG/DTA analysis and Vicker's microhardness test.
