Dinakaran, Paul M.; Kalainathan, S. published the artcile< Synthesis, growth, structural, spectral, linear and nonlinear optical and mechanical studies of a novel organic NLO single crystal 4-Bromo 4-Nitrostilbene (BONS) for nonlinear optical applications>, Related Products of 112-63-0, the main research area is bromo nitrostilbene single crystal NLO material; single crystal growth structural spectral linear NLO mech property.
Single crystal of 4-Bromo 4-Nitrostilbene (BONS), a new organic nonlinear optical material was synthesized and crystals were grown with dimensions up to 8 × 6 × 3 mm3 from Et Me ketone (EMK) solvent by slow evaporation method. Single crystal X-ray diffractometer was used to measure the unit cell parameters and confirmed the BONS structure as orthorhombic with the space group P212121. The sample has been subjected to powder X-ray diffraction to identify the crystalline nature and the prominent peaks were indexed. The functional groups were identified from Fourier transform IR (FTIR) spectral anal. Proton NMR anal. confirms the protonation in the structure of the title compound Optical behavior of BONS has been observed by UV-Vis absorption spectral anal. which shows the low cut off wavelength lies at 405 nm and found that the energy band gap of the crystal is 2.90 eV. Thermal stability of the material has been confirmed by TG/DTA analyses. The BONS compound formation analyzed by mass spectroscopic anal. The mech. strength of the crystal was found using Vickers microhardness measurement. The laser damage threshold (LDT) for the grown crystal was measured by using Nd:YAG laser. Photoluminescence spectrum indicated green light emission at 515.44 nm. The Kurtz powder second harmonic generation test shows that the BONS crystal (1.5 V) is a very potential NLO candidate for optical generation and it has SHG efficiency 69 times greater than that of KDP (21.7 mV).
Optical Materials (Amsterdam, Netherlands) published new progress about Band gap. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Related Products of 112-63-0.
