Investigation on the Linear and Nonlinear Optical Properties of L-Lysine Doped Ammonium Dihydrogen Phosphate Crystal for NLO Applications

Abstract

In present investigation L-lysine doped ADP crystal has been grown by slow evaporation technique. The crystalline nature of the grown crystal was confirmed using powder X-ray diffraction technique. The optical studies were carried to examine optical transparency and determine the optical constants of the grown crystal quenching the optoelectronics applications. The optical band gap of grown crystal is found to be 4.7eV. The third order nonlinear behaviour has been investigated using Z-scan technique at 632.8 nm. The nonlinear third order susceptibility of grown crystal is found to be 1 .578 x 10-5 esu. The nonlinear index of refraction and absorption coefficient were determined to explore the optical limiting applications of the grown NLO crystal. The kurtz powder test confirmed the second harmonic generations by the grown crystal.

Dielectric, etching and Z-scan studies of glycine doped potassium thiourea chloride crystal

“…2a which evidences the decreasing behavior of dielectric constant of pure and glycine doped potassium thiourea chloride crystal with increasing frequency. The high polarization activity in lower frequency domain leads to higher dielectric constant while the low polarization activity at higher frequencies results in reduction of dielectric constant of crystals [12]. As organic groups favor lower dielectric activity, substantial reduction in magnitude of dielectric constant of glycine doped potassium thiourea chloride crystal is observed in comparison to PTC crystal.…”
