Effect on Doping of Basic Violet in Structural and Optical properties of KDP Crystal.

The Potassium Dihydrogen Orthophosphate (KDP, KH2PO4) pure single crystals and doped with Basic Violet (Crystal Violet, C25H30ClN3) dye, were successfully grown by slow evaporation method at room temperature with deionized water as a solvent to the vision of improve properties of KDP crystal. Two different concentration of Basic Violet dye 0.1mol% and 0.2mol% were considered while synthesis of KDP crystal. The Energy Dispersive X-ray Analysis (EDAX) confirms the presence of Basic Violet dye in grown crystals. A tetragonal structure of all three crystals was confirmed and the value of lattice parameter was calculated by X–Ray diffraction (XRD) analysis. UV-VIS Spectroscopy studies transparency of crystal and optical band gap is slight differ of pure and Basic Violet doped crystal. Raman Spectroscopy also studies structural mode of bond in all crystal. [ABSTRACT FROM AUTHOR]
