Abstract

Silver nitrate doped potassium zinc phosphate hexahydrate NLO single crystal was grown using conventional solution growth technique. The as grown single crystal was subjected to single crystal X-ray diffraction and it was revealed that crystal belongs to monoclinic system. Photoluminescence spectra was observed at 415 nm and 545 nm due to the ?* - n and ?- ?* transitions. Photoconductivity was measured to understand the internal processes in crystals. The negative conductivity of the as grown crystal may be due to the reduction in number of charge carries in the presences of radiation. Thermal properties of silver nitrate doped potassium zinc phosphate hexahydrate were studied and it was found that the melting point of as grown is 1230 C. Microhardness of silver nitrate doped potassium zinc phosphate hexahydrate was also studied and concluded that it belongs to soft material. Electrical property of as grown crystal was also carried out.
