“…Generally, organic crystals possess high optical nonlinearity but poor mechanical strength, thermal stability and low laser damage threshold whereas an inorganic possess better mechanical strength and high thermal stability although they show relatively low nonlinearity due to the shortfall of extended π-electron delocalization [2].The problems can be overcome by new type of compound called semiorganic. Literature elucidate that semiorganic material shows the properties of high non-linearity of organics with better mechanical and thermal stability of the inorganic [3][4][5][6][7][8][9][10][11]. Hence, semi-organic materials are made an attention by material researchers.…”

“…In recent years, there are many thiourea based materials are reported with high second harmonic efficiency (SHG) than the commercial material potassium dihydrogen phosphate (KDP). The SHG efficiency of reported materials are bis(thiourea) ammonium nitrate (1.52 times > KDP) [3], bis(thiourea) cadmium formate (2 times > KDP) [20], bis(thiourea) zinc acetate (2 times > KDP) [21], bis(thiurea) zinc chloride (1.75 times > KDP) [22] and bis(thiourea) strontium chloride (BTSC) (1.54 times > KDP) [23].…”

A semiorganic nonlinear optical (NLO) single crystal of bis(thiourea) manganese chloride (BTMC) is grown successfully by slow cooling technique using water as solvent at temperature 45 °C. The optically good quality crystal of BTMC was grown with dimension up to 8 × 8 × 2 mm 3 in a period of 2-3 weeks. The grown crystal crystallizes in orthorhombic crystal system which was confirmed by single crystal X-ray diffraction analysis. The various functional groups of BTMC were identified through FT-IR spectroscopic analysis. The lower cutoff wavelength of 280 nm was revealed from optical transmittance spectrum of UV. The mechanical behavior of BTMC crystal was analyzed by Vicker's microhardness study and also the various mechanical parameters were determined. Vickers micro hardness test revealed, the titular crystal belongs to harder material category. The SHG efficiency is estimated from Kurtz-Perry powder method and it found to be 0.33 times than the reference material. The dielectric behavior, photo conducting nature and surface properties have been analyzed for grown BTMC crystal. The presence of synthesized elements was confirmed by EDAX study. The third order nonlinear optical susceptibility (3) of the material is measured using Z-scan technique and it is found to be 5.1202 × 10 −14 esu.

Alkali metals (Li, Na, K) doped anthracene high quality organic crystals were grown by slow evaporation at ambient environment. The relative occupancy of dopants and its influence of AN lattice phonons has been probed using elemental and diffraction analysis respectively. These alkali metal ions act as an efficient optically active sites, thereby projecting enhancement in UV region and photoluminescence studies. The nonlinear susceptibility (χ(3)) have been evaluated for doped crystals from Z ‐ scan technique and the values of these parameters found to be 10−2 esu which was higher than reported organic crystals. The incorporation of the alkali metal ions progressively alters melting point, overtone vibrational bands, mechanical strength and nonlinear optical properties for the grown crystals. The improved thermal, mechanical, linear and nonlinear optical properties of doped crystals make it as a better candidate for optoelectronic applications.
