Abstract
Pure and 0.1 mol% amaranth dye doped sodium acid phthalate (SAP) crystals were grown by slow evaporation technique. Doping of the dye resulted in light pink colored crystals without changing its morphology. PXRD revealed no extra peak as a result of doping. The dye doping altered Raman peak intensities due to the presence of organic functional groups. Doped crystals showed the enhanced dielectric constant value ∼170. The dielectric constant showed very small variation with temperature, which is useful in high temperature dielectric and piezoelectric devices. The piezoelectric charge coefficient increased from 1 pC/N to 2 pC/N as a result of dye doping. Ferroelectric P-E loops for the grown crystals were traced at room temperature, which revealed the enhancement in polarization due to dye doping. The hardness parameters and elastic stiffness were found to decrease as a result of dye doping in SAP crystals.
