【摘要】 Multifunctional ceramics of 0.825K_0.5Na_0.5NbO₃-0.175Sr(Yb_0.5Nb_0.5)O₃-x%Er with ferroelectric,transparent and luminescent properties were obtained by doping Er.The effects of Er-doping on the structure,luminescence and electrical properties of the ceramics were studied.After Er doping,the ceramics have luminescent properties and the luminescence intensity reaches the maximum when x=0.75.The ceramics still have good light transmission,but the transmittance decreases with the increase of Er-doping content due to the change of phase structure from pseudo-cubic phase to three-phase orthogonality.The energy storage properties is also greatly improved,and the W_rec and the η of the ceramics reach the maximum value of 0.31 J/cm³ and 94.6% when x=0.25,respectively.At the same time,the maximum electro-induced strain value is 0.031%.更多还原
