Abstract
Abstract
Nonlinear optical single crystals of L-histidine nitrate (LHN) as well as 0.05 mol % Y2+ doped LHN and 0.10 mol % Y2+ doped LHN were successfully grown by slow evaporation technique at room temperature. The lower cutoff wavelength and transmittance were 339 nm, 343 nm, 347 nm and 84 %, 86 % and 87 % for LHN, 0.05 mol % and 0.10 mol % yttrium doped LHN, respectively. Powder XRD studies revealed that the grown materials belong to an orthorhombic system with the space group P212121. FT-IR peak at 534 cm−1 due to yttrium coordinated with oxygen was observed. The EDAX analysis confirmed the presence of such elements as C, N, O and Y in the grown materials. High intensity PL emission peak was obtained at 420 nm.
