L-proline cadmium chloride (LPCC) crystals doped with L-tartaric acid were grown by solution method. Solubility was measured for the samples at different temperatures from 30 oC to 50 oC. Single crystal XRD studies have been carried out to identify the crystal structure. Microhardness was measured to find the mechanical strength of the samples. SHG efficiency and laser damage threshold (LDT) values were determined for the samples. Dielectric constant and loss factor of the grown crystals were determined at different frequencies and temperatures. Photoconductivity was measured for the undoped and L-tartaric acid doped LPCC samples by applying various electric fields.
