Growth of organic single crystal by transparent vertical bridgman technique and its characterization

Abstract

Organic single crystal of benzyl carbamate was grown by transparent vertical Bridgman technique. The grown crystal was subjected to single-crystal XRD, optical transmittance analysis, second harmonic generation analysis, laser damage threshold and photoconductivity analysis. The grown crystal cell parameters were confirmed by single-crystal X-ray diffraction analysis. From the UV–Vis– NIR transmittance spectrum analysis the cut off wavelength was found to be 275 nm. The second harmonic generation property of the powdered benzyl carbamate was confirmed by the emission of green light. The powder density value of benzyl carbamate crystal was found to be 0.955 GW/cm2 . Benzyl carbamate showed positive photoconductivity nature and the calculated photosensitivity value was 2.84.
