1：Experimental Design and Method Selection:

The study involved growing pure and glycine doped KDP single crystals using the slow solvent evaporation technique. The crystals were then analyzed using single crystal X-ray diffraction, UV-Vis spectroscopy, Kurtz-Perry powder test for SHG efficiency, dielectric measurements, and microscopic etching studies.

2：Sample Selection and Data Sources:

AR grade potassium dihydrogen orthophosphate (KDP) salt was used to prepare a homogeneous supersaturated solution, to which 0.5 mol% of glycine dopant was added.

3：5 mol% of glycine dopant was added. List of Experimental Equipment and Materials:

3. List of Experimental Equipment and Materials: Equipment included a single crystal X-ray diffractometer (Enraf Nonius CAD4), UV-1601 spectrophotometer (Shimadzu), Q-switched Nd:YAG laser for SHG testing, HIOKI-3532 LCR meter for dielectric measurements, and a Carl Zeiss optical microscope for etching studies.

4：Experimental Procedures and Operational Workflow:

The glycine doped KDP solution was filtered and allowed to crystallize in a vibration-free environment. The grown crystals were then subjected to various analyses to determine their properties.

5：Data Analysis Methods:

The data from each analysis were interpreted to understand the impact of glycine doping on the KDP crystal's properties.
