Pure and barium added strontium tartrate trihydrate single crystals were grown using silica gel by chemical reaction method at room temperature. The DC conductivity measurements were carried out on the crystals. The Arrhenius plots show that two types of conduction exists in these crystals-one at low temperature and the other at high temperature in the form of extrinsic and intrinsic conduction, respectively. Within the temperature range considered in the present study these crystals do not exhibit ferroelectric transitions.Keywords

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
