Growth and characterization of organic Nonlinear optical material: acenaphthene DL- malic acid (ADLMA)

Organic single crystals of nonlinear optical material Acenaphthene DL-malic acid (ADLMA) have been grown successfully by the slow evaporation solution growth technique. To begin with, solubility tests were carried out for two solvents such as acetone and chloroform-methanol. Among the two solvents, the solubility of ADLMA was found to be the highest in chloroform-methanol, so crystallization of ADLMA was done from its aqueous solution. The elemental percentage of the material was carried out CHN analysis. The crystalline nature of ADLMA crystal was confirmed by the powder X-ray diffraction study and diffraction peaks were indexed. Vibration modes of the functional groups were recognized and studied by recording a FTIR spectrum. The optical transparency range and absorption has been studied throughout UV-Vis-NIR spectroscopy. The second harmonic generation efficiency of the grown ADLMA crystal has been obtained by the KurtzPerry powder technique. The grown crystals were subjected to TG/DTA analysis. The dielectric activities of the title compound crystal was investigated and measuring the dielectric loss and dielectric constant properties. The photoluminescence spectrum was also studied..
