Growth and Characterization of Pure and Methionine Doped Potassium Pentaborate (KBO5) Single Crystals

Abstract

Potassium pentaborate (KB 5 O 8. 4 H 2 O or K(H 4 B 5 O 10).2H 2 O or KBO 5) single crystals were grown by slow evaporation solution growth method at room temperature and the properties of the grown crystals were investigated. L-Methionine doped Potassium pentaborate (LMPPB) single crystals were grown by slow evaporation solution growth method and the characterization for the obtained materials were done using powder x-ray diffraction, FT-IR, UV-Vis and thermal analysis methods. Powder X-ray diffraction studies were carried out to determine the crystal structure and lattice parameters of the grown crystals by using powder-x software.. The optical transmittance of the crystal was determined by recording UV-Vis spectrum. pure KBO 5 and L-Methionine potassium pentaborate (LMPPB) single crystals were synthesized from its aqueous solution at ambient temperature. XRD confirmed the orthorhombic nature of the crystals. The UV-Vis spectroscopy highlighted the transparent nature of the LMPPB crystal. The various functionalities slot in the synthesized compound were analysed by FT-IR technique. The TGA analyses showed the thermal stability and the melting point of LMPPB.
