摘要：

A series of Ho3+ doped Bi1/2Na1/2TiO3 (BNTO: x Ho3+, x=0.0, 0.002, 0.005, 0.01, 0.02, 0.03, 0.04, 0.05, and 0.07) ceramics were synthesized by a solid-state reaction, and their structural, photoluminescence, and ferroelectric properties were investigated. Bright green emission of BNTO: x Ho3+ was first observed at room temperature, and what is more, the green emission can be directly excited by blue light radiation which indicates BNTO: x Ho3+ can act as a highly efficient phosphor. Furthermore, the optimized photoluminescence is observed in BNTO: x Ho3+ with x=0.01 sample which also shows good ferroelectric properties. It is believed that BNTO: x Ho3+ with x=0.01 may act as a potentially multifunctional optical-electro material. (C) 2013 Elsevier B.V. All rights reserved.
