采用助熔剂法生长了掺Eu的0.91Pb（Zn 1/3 Nb 2/3）O3-0.09PbTiO3（PZN-9 PT：Eu）单晶。研究了晶体的相结构、铁电、介电和光致发光性能。PZN-9 PT：Eu晶体具有纯钙钛矿结构。剩余极化强度Pr为36.7664 μC/cm ~ 2，矫顽场Ec为11.0597 kV/cm，总双极应变为0.35%，单极应变为0.12%。PZN-9 PT：Eu晶体的矫顽场E_c比PZN-9 PT晶体的矫顽场E_c高3倍。PZN-9 PT：Eu晶体的居里温度Tc约为172 °C，略高于PZN-PT单晶的居里温度Tc。在464 nm激光激发下，在593 nm、613 nm、657 nm和716 nm附近出现4个宽带峰，分别对应于5D 0 → 7 FJ（J= 0，1，2，3，4）跃迁发射。在298 ~ 393 K范围内，所有发射峰的发光强度随温度的升高而降低。研究结果可为光电器件用多功能材料的设计提供新的思路。
Eu3+-doped 0.91Pb(Zn1/3Nb2/3)O3-0.09PbTiO3(PZN-9PT: Eu) single crystals were grown by the flux technique. The phase structure, ferroelectric, dielectric, and photoluminescence properties of the crystal were investigated. The PZN-9PT: Eu crystal has a pure perovskite structure. The residual polarizationPr, coercive fieldEc, total bipolar strain, and unipolar stain are 36.7664 μC/cm2, 11.0597 kV/cm, 0.35%, and 0.12%, respectively. The coercive fieldEcof PZN-9PT: Eu crystal is three times higher than that of PZN-9PT crystal. The Curie temperatureTcof the PZN-9PT: Eu crystal is about 172 °C which is slightly higher than that of PZN-PT single crystal. Under the excitation of 464 nm laser, four broadband peaks appear around 593 nm, 613 nm, 657 nm, and 716 nm, corresponding to the5D0→7FJ(J= 0, 1, 2, 3, 4) transition emission, respectively. The luminescence intensity of all the emission peaks decreases with increasing temperatures range from 298 to 393 K. Our results can provide a new way for the design of multifunctional materials used in optical-electrical devices.
