In this work, 0.15Pb(Er1/2Nb1/2)O3−0.63Pb(Zn1/3Nb2/3)O3−0.22PbTiO3 (15PEN−63PZN−22PT) single crystals with a pure perovskite structure are obtained through the flux method. The phase structure, dielectric, ferroelectric properties and upconversion photoluminescence of the crystals are studied. The ternary crystals along the [110] orientation have a high Curie temperature (Tc = 250 °C) and large coercive field (Ec = 11.0597 kV/cm) which are higher than those of crystals reported previously. Furthermore, the PEN−PZN−PT crystals are produced with a strong green light excited by a 980 nm laser. Being in the range 298−478 K, the emission intensity of all peaks decreases with increase in temperature. The absolute quantum yield (QY) for the crystals is 0.00059%. These excellent properties provide new possibilities for multifunctional materials of optoelectronic devices. |
