Abstract
The solvent evaporation technique was adopted for growing a single crystal of potassium DL-malato borate. The crystalline behavior of the grown material was confirmed due to the formation of the distinct sharp peak in the powder XRD spectrum. The material crystallizes into the orthorhombic system with space group Pna21. The structural analysis confirms the occurrence of potassium and boron in the grown crystal. FTIR analysis was carried out to know about various functional groups present in the grown crystal. The cut-off wavelength and bandgap energy of the material were 212 nm and 5.27 eV, respectively. The thermogravimetric analysis was used to analyze the thermal stability of the compound and the material was thermally stable up to 96°C. The second-order nonlinear efficiency of the material was found to be 0.85 times that of KDP crystal.
