Effect of Added Impurities on the Properties of LAHCL Single Crystals

L-arginine hydrogen chloride (LAHCl) is the material of interest in our study which has peculiar optical, nonlinear and dielectric properties. This study is carried out for knowing about the influence of organic and inorganic impurities on the physical and chemical properties of LAHCl single crystals. Slow cooling technique is employed to grow both pure and impure LAHCl crystals. The obtained crystals were then exposed to micro hardness, dielectric measurements and AC conductivity measurements. This aids in understanding the physical properties of the developed crystals. Kurtz and Perry second harmonic generation test was used to confirm the optical and non-linear properties of the grown crystals. It was found to be approximately 5 times that of potassium dihydrogen orthophosphate crystal. The outcomes and conclusive results are discussed in detail.
