Unidirectional growth of organic nonlinear optical l-arginine maleate dihydrate single crystal by Sankaranarayanan–Ramasamy (SR) method and its characterization

摘要: Abstract Unidirectional organic nonlinear optical l -arginine maleate dihydrate (LAMD) single crystal has been successfully grown by the Sankaranarayanan–Ramasamy (SR) method. The SR as-grown was transparent and size 65 mm in length 15 mm diameter. LAMD crystals have subjected to X-ray diffraction, high-resolution diffraction (HRXRD), piezoelectric, dielectrics, UV–vis–NIR, Vickers microhardness second harmonic generation (SHG) efficiency study results were discussed. lattice parameters of are confirmed morphology is investigated conventional crystal. Crystalline perfection observed from HRXRD analysis. Piezoelectric charge coefficients determined. dielectric constant loss measurement made as function temperature range between 40 140 °C. improved transparency recording UV–vis Microhardness measurements reveal that mechanical strength SR-grown higher than method SHG indicate at a fundamental wavelength 1064 nm roughly 1.4 times KDP.
