Phase engineering in NaNbO3 antiferroelectrics for high energy storage density

Enhancement of the photoluminescence modulation ratio in highly transparent KNN-based ceramics for optical information storage

“…13,15,21 This all-optical exchange (light modulates light) can avoid electro-optical or photoelectric conversion and simplify the information transmission. Third and exhilaratingly, RE ion doping may inhibit grain growth and make the KNN ceramics transparent; meanwhile the transmittance could change when illuminated by light as well, [22][23][24][25] which brings transparent KNN ceramic prospects for smart windows. 10 More excitingly, the transparency could bring about a qualitative leap for optical information storage.…”

Achieving outstanding temperature and frequency stability in NaNbO3-modified (Ba0.94Li0.02La0.04)(Mg0.04Ti0.96)O3 pulse energy storage ceramics

“…7(b) demonstrates the comparison of the energy-storage properties of the 0.85BLLMT-0.15NN sample with other lead-free ceramics. 7,[11][12][13][19][20][21][29][30][31][32][33][34] The 0.85BLLMT-0.15NN sample has dual priority values of W rec and h than other lead-free ceramics, which is caused by the high BDS value, reduced domain size, and multiphase coexistence in the system. Such an improvement is correlated with the O and R phases that can provide more polarization orientation than the T phase, enhancing the P max value.…”

Visible–Near‐Infrared Diffuse Reflectance and Optical Energy Gap of Sodium Niobate Modified by Mn Ions: Na(Nb1−zMnz)O3 and (Na1−xBix)(Nb1−yMny)O3 Compounds Study

“…[ 16–22 ] Moreover, NaNbO 3 attracts attention because its flexible structure enables the appearance of new phases and further applications. [ 23–27 ]…”

“…[16][17][18][19][20][21][22] Moreover, NaNbO 3 attracts attention because its flexible structure enables the appearance of new phases and further applications. [23][24][25][26][27] The Nb 5d metal and oxygen O 2p ion states form a wide gap in the electronic structure of perovskite Na 1þ Nb 5þ O 2À 3 . The pure, transparent NaNbO 3 crystals show the optical energy gap E gap ¼ 3.2-3.5 eV.…”

“…Such properties were reported for the NaNbO 3 -based composites. [24][25][26][27]49] A high electric field can induce AFE to FE transformation when applied during the energy storage preparations. Hence, reversibility of this effect is needed.…”
