The non-linear sodium para-nitrophenolate dihydrate (SPNPD) single crystals were grown by slow evaporation method. The powder X-ray diffraction analysis was carried out on the fine crystalline powder sample to confirm the crystalline nature of the grown crystal. Various functional groups and chemical bonding were identified by FTIR. In the photoluminescence spectrum, a sharp broad emission peak centered at 544 nm indicates green emission. The SHG efficiency of this material was found to be 4.15 times that of KDP which confirms that the grown crystal is a very good to achieve high SHG efficiency.
