Abstract :
A new Non-linear optical material L-tyrosine Guanidine Carbonate single crystal is synthesized by slow evaporation solution growth technique at room temperature using water as solvent. Good transparent LTGC crystal is sized. Single crystal X-ray diffraction reveals the crystal belongs to the Tetragonal P structure and a space group of P41212. The sharp intense peak in Powder XRD analysis confirms the good crystalline nature and purity of the crystal. The presence of various functional groups and their modes of vibration were identified by FTIR spectral analysis. The UV-Vis spectroscopic study shows that the lower cut-off wavelength is 234.6 nm with wide transparency range and very low absorbance. The optical band gap spectrum shows the Energy gap of the crystal is about 5.6 eV. The LTGC was subjected to fluorescence analysis and it was ascertained that the maximum emission was in green region at 532.4 nm. The mechanical behavior was studied by Vickers microhardness test.
