Picosecond near-to-mid-infrared absorption of pulse-injected small polarons in magnesium doped lithium niobate

Freytag, Felix; Booker, Philip; Corradi, Gabor; Messerschmidt, Simon; Krampf, Andreas; Imlau, Mirco (Washington, DC : Optical Society of America, 2018)

Femtosecond-pulse-induced (Epump = 2:5 eV) picosecond infrared absorption is studied in the spectral region between 0.30 eV and 1.05 eV in LiNbO3:Mg. We find a noninstantaneous mid-infrared absorption peak in the time ...
Sol–gel synthesis and structural characterization of band gap engineered ferroelectric perovskite oxide potassium sodium barium nickel niobate

Balanov, Vasilii A.; Zhao, Zhijun; Pan, Mingjing; Feldhoff, Armin; Bai, Yang (Dordrecht [u.a.] : Springer Science, 2020)

Ferroelectric materials with engineered thus visible-range optical band gaps are increasingly researched in recent years, triggering potentially new applications in solar cells, opto-ferroelectric devices, multifunctional ...
