N2 - The electro-optical (E-O) properties of relaxor ferroelectric single crystals have received extensive attention in recent years, but their light transmittance is still a major obstacle limiting their optical properties. This study successfully grew the Eu-doped Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) relaxor ferroelectric single crystal using the modified Bridgman method. The Eu-PIN-PMN-PT crystal had high piezoelectric properties, high coercive fields, and temperature stability. The dielectric behavior at low temperatures showed that the Eu-PIN-PMN-PT crystal had more polar nano-regions (PNRs) than the undoped PIN-PMN-PT crystal to improve its piezoelectric properties. A thorough evaluation of the full matrix of electromechanical parameters was conducted, yielding a comprehensive understanding of the material's properties in different directions. Meanwhile, after polarization along the [110] direction, the crystal obtained a high transmittance along the [001] direction, and an effective electro-optical coefficient of up to 420 pm/V was measured at room temperature. Due to excellent comprehensive properties, Eu-PIN-PMN-PT crystals are expected to be ideal materials for piezoelectric and electro-optical devices.
