Luminescence and structural study of Bi4−xEuxTi3O12 solid solution

Composition dependence of the multifunctional properties of Nd-doped Bi4Ti3O12 ceramics

“…Refinements using the tetragonal space group yielded a perfect fit for the higher doped samples. Similar structural phase transformations by increasing the dopant concentration has been reported for other Ln-dopants as well (e.g., for La near x = 0.86 [44], for Eu near x = 1.2 [38], and for Sm/Fe near x = 0.4 [45]). The lattice parameters of the BNTO samples are presented in Fig.…”

“…As mentioned, Bi 4 Ti 3 O 12 has well-established high temperature ferroelectric properties [22,23], that can be enhanced by the substitution of Bi by Nd causing enlarged remnant polarization [24][25][26] accompanied by other changes of structural and physical properties [27][28][29][30][31]. Recently, there have been several investigations on the effects of doping Bi 4 Ti 3 O 12 by various magnetic species [32][33][34][35][36][37][38]. However, these materials do not acquire magnetic long range order even at low temperatures.…”

Red-orange photoluminescence and dielectric relaxation of Eu3+-doped Bi2Ti2O7 pyrochlore structure thin films

“…We noted that in Fig. 1(a) [18,19]. This possibly implies that Eu 3þ ions can stabilize the cubic pyrochlore structure.…”

Blue excited photoluminescence of Pr doped CaBi2Ta2O9 based ferroelectrics

“…These rare earth doped BLSFs show novel photoluminescent properties while retaining the ferroelectric functions. So it has been of considerable importance in designing materials for integrated optoelectronic applications [9][10][11][12][13][14][15]18,19]. However, the photoluminescence of the rare earth doped BLSFs is only achieved under ultraviolet or infrared light excitation; there are few reports about the blue excited luminescent properties of BLSFs.…”
