Studies on growth, structural, optical and mechanical properties of xylenol orange dye admixtured L-arginine phosphate single crystal

Bulk single crystals of pure and xylenol orange (XO) admixtured L-arginine phosphate (LAP) were grown by slow cooling technique. The cell parameters and crystallinity of pure and dye admixtured LAP crystals were confirmed by single crystal and powder X-ray diffraction analyses. HRXRD analysis reveals the presence of xylenol orange dye in interstitial site of LAP crystal lattice and it confirms the crystalline perfection of grown crystals. The functional groups of grown crystals were confirmed by FTIR spectral analysis. UV-vis transmission studies show the characteristic absorption of xylenol orange admixtured LAP crystal. Vickers' microhardness and laser damage threshold studies were carried out on these crystals. Kurtz and Perry powder test was conducted to measure the second harmonic generation efficiency of pure and dye admixtured LAP crystals. (c) 2013 Elsevier GmbH. All rights reserved.
