Abstract

In the present study the single crystal growth of the pure and doped organic nonlinear optical crystal, L-arginine phosphate is reported. The dopants used were urea and thiourea. The crystals were grown by slow evaporation technique. The presence of various functional groups in the grown crystal was confirmed by Fourier transform infrared (FT-IR) analysis. The thermal properties of the grown crystals were studied by thermo gravimetric and differential scanning calorimetry analysis (TG/DSC). Second harmonic generation (SHG) measurement was used to confirm the organic nonlinear optical properties of the grown crystal.
Keywords: Growth from solutions; nonlinear optical materials; thermal analysis; doped LAP.
