crystal growth and characterization of 2-amino-4,6-dimethylpyrimidium 3,5-dinitrobenzoate dihydrate (2apdbd) single crystal for nonlinear optical (nlo) application

Single crystal of 2-amino-4,6-dimethylpyrimidium 3,5-dinitrobenzoate dihydrate (2apdbd) was grown by solution growth technique. the x-ray diffraction reveals that 2apdbd crystal belongs to a centrosymmetric triclinic crystal system with space group p-1. the uv visible-nir spectra confirm a peak at 350 nm with lower cut off wavelength shows a wide transmission window in the entire visible region. the electrical characteristics of 2apdbd crystal have a low density of defects and a low value of dielectric loss found from the dielectric studies.  to find out the third order nonlinear susceptibilities (χ(3)) z-can analysis was used.
