Abstract
AbstractThe synthesis as well as the results of the investigations on the structure as well as properties ‐ thermal, mechanical, surface and nonlinear optical of semiorganic bisglycine lithium perchlorate (BGLP) single crystals are herein recorded. BGLP single crystal with dimensions 14× 3 × 2 mm3 has been synthesized and its structure and lattice parameters have been identified with the aid of X‐ray diffraction. The vibrational spectrum of BGLP has been investigated making use of FT‐IR and FT‐Raman spectra. Optical transmittance and absorption is examined by UV–vis spectroscopy with thickness 2 mm and it is shown that the crystal is highly transparent with a lower cut‐off of 287 nm. The optical bandgap is evaluated as 5.7 eV. The dielectric constant is found to show variations with frequency as well as temperature, which remains constant at high frequencies. Dielectric loss is found to decrease with the applied electric field. BGLP is manifested to be thermally stable up to 256 °C as revealed from thermogravimetric analyses. The 2D nucleation mechanism in the growth of BGLP crystals is understood from etching studies. By implementing Z‐scan studies with a He─Ne laser as a source, the nonlinear absorption coefficient, susceptibility, and third order nonlinear refractive index are all computed.
