摘要：

Picolinium picrate monohydrate (PPM), an organic optical material, was synthesized and single crystals were grown by slow evaporation solution technique. The cell parameters of PPM were confirmed by single crystal X-ray diffraction analysis. The PPM crystals were subjected to FT-IR spectral analyses to confirm the synthesized compound. UV-vis-NIR spectral studies revealed that the optical transparency window of PPM crystal spreads over in the visible and NIR (480-900 nm) regions. From the transmittance data, the optical band gap as function of photon energy was estimated. The microhardness studies were carried out on PPM crystal. The laser damage threshold of PPM crystal was measured using Nd:YAG laser. (C) 2013 Elsevier GmbH. All rights reserved.
