Abstract
Potassium dihydrogen phosphate (KDP) is a well known nonlinear optical (NLO) material for various optoelectronics
applications. Since amino acids exhibits NLO property, it is of interest to dope them in KDP. In present study single crystal
of pure and amino acid, Glycine doped Potassium dihydrogen phosphate (KDP) has been grown by slow evaporation
solution growth technique. The SHG efficiency of pure and Glycine doped KDP crystal was confirmed by Nd:YAG pulsed
Laser employing the Kurtz powder technique. The SHG efficiency of Glycine doped KDP crystal was found to be 1.36 times
more than pure KDP. The crystallinity and cell parameters were characterized by X-ray diffraction analysis, the shifting in
frequency assignment of different functional groups of KDP due to addition of Glycine were analyzed by FTIR analysis. The
enhancement in transmittance of grown KDP crystal with addition of Glycine was determined by UV-Visible spectral
analysis. The presence of dopant in the sample of grown crystal was confirmed by energy dispersive X-ray analysis
(EDAX). The grown crystal was subjected to thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC)
analysis to observe the thermal decomposition and weight loss.
