Effects of compositional changes on luminescence of lead-free Eu3+-doped K1−xNaxNbO3 piezoelectric ceramics

Low-temperature thermometry based on upconversion emission of Ho/Yb-codoped Ba0.77Ca0.23TiO3 ceramics

“…It has been demonstrated that excellent luminescent performances can be obtained in RE doped ferroelectrics [16][17][18][19]. Moreover, it was also revealed that poling is an effective method to modify the emission intensity of RE doped ferroelectrics [20,21].…”

Effect of Er2O3 dopant on electrical and optical properties of potassium sodium niobate silicate glass-ceramics

“…By the way, the peaks of KNN phases (at 47 , 52 and 57 ) had a small shifted to the right because of Er 3+ have been entered into KNN crystals, resulting in a slight distortion in crystal structure. These results suggest that Er 3+ doped KNN structure exist between monoclinic to orthorhombic structure [16,17].…”

Improved piezoelectricity and luminescence behavior in Er2O3 doped (K,Na)NbO3 ceramics

“…Generally speaking, the rare earth ions doped perovskite oxide ceramics can also present the excellent luminescence effect [5][6]. In the last several years, the BaTiO 3 and Bi 0.5 Na 0.5 TiO 3 materials with perovskite ABO 3 structure have been confirmed to possess luminescence properties by Er 3+ ions doping [7][8].…”
