Optical and Dielectric Studies on L-Valinium Picrate Single Crystal
Journal of Crystallization Process and Technology
Single crystals of L-Valinium picrate were grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to monoclinic system. The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wave length has been found to be 470 nm. The optical band gap is found to be 2.55 eV. The transmittance of L-Valinium picrate crystal has been used to calculate the refractive indexdoi:10.4236/jcpt.2012.23015 fatcat:mwqpioqymnc4rjzcmcb26bfgaa
