ABSTRACT: Single crystals of glycine doped potassium acid phthalate (KAP) have been grown from low
temperature solution growth method by employing slow evaporation of the solvent at room
temperature. The grown crystal was subjected to various studies such as X-ray diffraction
(XRD), Fourier Transform Infrared (FTIR), UV-visible and Second Harmonic Generation (SHG)
studies. The thermal stability, mechanical strength and dielectric constant were also measured.
The various studies revealed the influence of the glycine on KAP and the investigations indicated
that glycine played an important role in the changes of the spectral, optical and mechanical
properties of KAP crystals.
