Article Preview

A nonlinear optical material Niobium doped L-Prolinium Picrate was synthesized and grown as single crystals by slow evaporation method. The grown crystals were subjected to structural, elemental, thermal, optical and dielectric studies. The structural analysis reveals that Nb : LPP belongs to the monoclinic crystallographic system with space group P21. Optical transparency of the grown crystals was investigated by UV-vis-NIR spectrum. The thermal analyses reveal that Nb doped L-Prolinium Picrate is thermally stable up to 185 °C. The dielectric constant and dielectric loss of the crystal were studied as a function of frequency. The nonlinear optical property of the grown crystal was confirmed by the Kurtz-powder second harmonic generation test and the results are compared with pure LPP. Mechanical strength of the crystal was also carried out by Vicker’s micro hardness test.
