摘要：

A semiorganic crystal of L-tyrosine hydrochloride, having dimensions up to (7 mm x 5 mm x 3 mm) has been grown by slow evaporation technique. The grown crystal was characterized by CHNS, UV-visible study and DSC analysis. The lower cut off wavelength of grown crystal is below 300 nm and has a wide transparency window, which is suitable for second harmonic generation. Photoluminescence study was also carried out. DSC analysis confirms that the crystal is stable up to 240 degrees C. The dielectric measurement of the crystal was studied as function of temperatures with three different frequencies. Photoconductivity of the sample revealed its positive photoconductivity nature. The second harmonic generation efficiency of crystal was tested by modified Kurtz-Perry powder technique.
