Raman, Photoluminescence, A.C.Electrical Studies of Pure and L-serine Doped Ammonium Dihydrogen Phosphate Single Crystals: The Understanding of Defect Chemistry in Hydrogen Bonding

Abstract

The ammonium dihydrogen phosphate (ADP) crystals have wide range of nonlinear optical applications. The hydrogen bond side chain contained dopant like L-serine causes the defect in ADP. The pure and L-serine doped ADP crystals are grown using slow evaporation technique. The powder XRD patterns show the single-phase nature of pure and doped ADP crystals. The FT-Raman shows presence of variety of normal modes of vibrations of ADP. The photoluminescence study suggests increase of the Stokes shift and presence of vibrational energy relaxation phenomena. The A.C.electrical studies like dielectric, impedance and modulus spectroscopy is done to felicitate the behaviour charge carrier under the course of the alternating electrical field. The defect oriented Correlated Barrier Hopping (CBH) conduction mechanism, presence of grain and grain boundary, non-Debye type relaxation etc. phenomena is explained presently. The nonlinear second harmonic generation efficiency of grown crystals is found to be improved on doping L-serine in ADP.
