Abstract:Bulk size of urea barbituric acid single crystal which have not been reported earlier was successfully grown by slow evaporation solution growth method. Single-crystal XRD brought out the lattice constant and the crystal system is observed to be monoclinic with space group P. Functional group of UBA were determined by FT-IR. Title crystal is entirely visible from 270 to 900 nm with linear optical energy gap value to be 4.50 eV. The observed HOMO-LUMO energy gap was 5.21 eV. Thermally, UBA crystal is found to b… Show more
