Synthesis and nucleation studies on L-leucine hydrobromide: a promising nonlinear optical material

A detailed study on nucleation kinetics, including metastable zone width and induction period, of semi-organic L-leucine hydrobromide led to the growth of good quality bulk size crystals. The structure and its perfection were assessed by powder X-ray diffraction, the etch pit method and high-resolution X-ray diffraction. Photoluminescence, time-resolved photoluminescence and Z-scan measurements were carried out for the assessment of optical and nonlinear optical properties.
