Bulk single crystals of L-histidine-4-nitrophenolate 4-nitrophenol (LHPP) a new organic material have been successfully grown for the first time using slow evaporation solution growth technique at room temperature Good optical quality single crystal of dimension up to 7 x 3 x 2 mm(3) has been obtained The grown crystals have been analyzed with X-ray diffraction vibrational spectral and thermal measurements The Kurtz powder technique has been adopted preliminarily to check the optical nonlinearity of the crystal Its optical behavior has been examined through UV-vis-NIR absorption and PL emission spectra They signify that the crystal is transparent in the region between 209 and 1200 nm To study the quality of the crystal SEM images have been recorded (C) 2010 Elsevier B V All rights reserved
