In this present work we have successfully grown L-alanine potassium nitrate (LAPN) single crystals by
spontaneous nucleation solution growth method. The crystal structure and lattice parameters of the grown LAPN
crystals have been determined using single crystal X-ray diffraction (SXRD) and powder X-ray diffraction
(PXRD) techniques. The functional groups present in the grown crystals have been identified by means of
Fourier transform infrared (FT-IR) analysis. Elemental analysis CHN was performed to confirm the inclusion of
potassium nitrate into the crystal lattice of L-alanine. The UV-Vis-NIR study has been carried out within 200-
2500 nm to determine the optical transparency and dielectric nature of the grown LAPN crystal. Second
harmonic generation (SHG) efficiency of the grown samples were studied by Kurtz-Perry technique using Nd:
YAG laser. The dielectric constant and dielectric loss of LAPN crystal was carried out as a function of frequency
and the obtained results were discussed. The photoconductivity nature of the grown crystal was confirmed from
photoconductivity analysis.
