Growth and characterization of an organic NLO crystal: 1-(4-methylphenyl)-3-(4-methoxyphenyl)-2-propen-1-one

Growth, characterization and crystal structure analysis of 1-(4-chlorophenyl)-3-(4-chlorophenyl)-2-propen-1-one

“…These data were used to get the optimal conditions for growing the single crystals similar to our earlier study [9]. It was found that the synthesized compound is insoluble in water and sparingly soluble in ethanol, methanol, etc., but it is moderately soluble in acetone, benzene, N,Ndimethylformamide (DMF).…”

“…There is currently much interest in organic NLO materials because of their large second-or third-order hyperpolarizabilities compared to inorganic NLO materials. Among the organic crystals reported for their second-harmonic generation (SHG), applications, Chalcone derivative are among the notable materials for their excellent blue light transmittance, good crystal stability, large nonlinear optical coefficients, and relatively short cutoff wavelengths of transmission [5][6][7][8][9].…”

Growth and characterization of chalcone derivative single crystal

“…The solubility of the compound is determined by adding the solvent to a known amount of compound, till it is completely dissolved in the solvent. To optimize the crystal growth conditions, the temperature dependence of the solubility in a solvent was determined from 30 to 50 1C by weighing method [6]. From this study, it was found that the synthesized compound was insoluble in water, sparingly soluble in ethanol, methanol and moderately soluble in acetone, benzene, N,N-dimethyl formamide (DMF), etc.…”

“…Organic crystals with the required conjugated pi electrons are attractive candidates, because of the large nonlinear optical coefficients. Their practical applications are limited by poor chemical stability, due to the presence of large n-conjugated system, which causes the red cut-off wavelength [6][7][8][9]. Their device applications are also impeded by their inadequate optical transmittance, poor optical quality, lack of robustness, low laser damage threshold and inability to grow into large size crystals.…”

“…In addition, they have large non-linear optical coefficients and relatively short cutoff wavelengths of transmission. The SHG performances of various chalcone derivatives are measured by powder technique using pulsed Nd-YAG laser was reported [6,10].…”
