TY - JOUR AU - Editor, Reviewing PY - 2010/12/16 Y2 - 2025/09/23 TI - Growth, Optical, Dielectric and Fundamental Properties of L-Arginine Acetate NLO Single Crystals JF - Recent Research in Science and Technology JA - RRST VL - 3 IS - 1 SE - Physics DO - UR - https://www.updatepublishing.com/journal/index.php/rrst/article/view/582 SP - AB - <p class="MsoNormal" style="line-height: normal; text-indent: 0in; margin: 0in 0in 0pt; mso-layout-grid-align: none;"><span style="font-family: ";Arial Narrow";,";sans-serif";; font-size: 10pt;">Some organic materials exhibit exceeding by large amount of nonlinear property and they are found to be more suitable for device fabrications. Hence, in the present study <span style="mso-bidi-font-weight: bold;">L-Arginine Acetate (LAA) </span>an organic material, has been extensively studied with regard to the growth and characterization. Single crystals of <span style="mso-bidi-font-weight: bold;">L-Arginine Acetate (LAA) with</span> good degree of transparency were grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to monoclinic system with space group P2₁. Some fundamental data such as valance electron, plasma energy, Penn gap,<span style="mso-spacerun: yes;">   </span>Fermi energy and electronic polarizability of the grown crystal were calculated. The optical absorption studies show that the crystal is transparent in the entire visible region with a cut off wavelength of 240 nm. The optical band gap is found to be 3.75 eV. The dependence of extinction coefficient (K) and refractive index (n) on wavelength has also been reported.<span style="color: #231f20;"> Dielectric constant measurements were carried out at different temperatures and frequencies.</span></span><span style="font-family: ";Arial Narrow";,";sans-serif";; font-size: 10pt; mso-fareast-font-family: Calibri;"> </span></p> ER -
