Composition design rule for energy harvesting devices in piezoelectric perovskite ceramics

Self-Growth of Centimeter-Scale Single Crystals by Normal Sintering Process in Modified Potassium Sodium Niobate Ceramics

“…The high dielectric loss of a giant grain is due to the metal vacancies. In addition, a high g 33 is also required at energy harvesting devices because a high d 33 xg 33 value indicates a high energy density4. An excellent d 33 xg 33 of 26,144 [ 10 −15   m 2 /N ] is observed in a giant grain of KNN-BCuN ceramics.…”

“…Pb-free ceramics have been studied to replace Pb(Zr,Ti)O 3 (PZT)-based ceramics, because Pb element causes environmental problems12345678910111213141516171819. Among the Pb-free ceramics, (K,Na)NbO 3 (KNN)-based ceramics have attracted the attention of many researchers, because of their high piezoelectric voltage coefficients which are required at the piezoelectric sensors45.…”

“…Among the Pb-free ceramics, (K,Na)NbO 3 (KNN)-based ceramics have attracted the attention of many researchers, because of their high piezoelectric voltage coefficients which are required at the piezoelectric sensors45. Their microstructure as well as crystal structure must be well-studied to obtain a promising piezoelectric performance in KNN-based ceramics.…”

An efficient gel-combustion synthesis of visible light emitting barium zirconate perovskite nanoceramics: Probing the photoluminescence of Sm 3+ and Eu 3+ doped BaZrO 3

“…Photoluminesence spectroscopy of Sm 3 þ doped BaZrO 3 A Sm 3 þ ion is a well known activator which gives bright photoluminescence in the visible and near infrared (NIR) region in various kinds of inorganic compounds. The emission bands observed for this particular ion are due to transitions between the energy levels in the 4f 5 to the f-f transitions are electronically forbidden and exhibit poor absorptivities in UV region.…”

“…This includes cheap solar cell [1], multiferroic material [2], energy harvesting device [3], photocatalysis [4], anode material in solid oxide fuel cell [5] etc. They can be tuned to different properties based on doping site i.e.…”
