Optical, P-XRD & U-V properties by varying the concentration of L-valine amino acid in pure KDP

Abstract EN

H2PO4 potassium dihydrogen phosphate crystals (KDP) were prepared for dopant L- valine amino acid.

The bulk growth was reported along <011> and <101> plane by seed rotating crystal method and solution growth method.

The doping concentrations in the mother solution were 0.4 mole%, 0.6 mole% and 0.8 mole% and the corresponding seed rotation rates were 30 rpm, 60 rpm and 100 rpm for 15 to 20 days.

KDP crystal of dimensions 102 x 23 mm, 72 x 23 mm and 102 x 35 mm size has been grown.

FTIR spectra showed the presence of functional groups in the crystal.

Powder X-ray diffraction analysis of transparent bulk nonlinear optical crystal doped with LV confirms the formation of the tetragonal system.

Energy Dispersive X-ray analysis (EDAX) confirms the elemental analysis of potassium and phosphate radicals in the reported crystal.

Optical transmission increases with the increase of concentration of L-valine in KDP crystals.
