Effect of Yb3+ doping level on the structure and spectroscopic properties of ZnO optical ceramics
(Institute of Physics Publishing, 2021) Gorokhova, E.; Venevtsev, I.; Alekseeva, I.; Khubetsov, A.; Dymshits, O.; Basyrova, L.; Oreschenko, E.; Eron’ko, S.; Muktepavela, F.; Kundzins, K.; Zhilin, A.; Loiko, P.
Zinc oxide optical ceramics with hexagonal structure doped with 0.6 –5.0 wt% Yb were fabricated by uniaxial hot pressing of commercial oxide powders at 1180 °C in vacuum. The ceramics were characterized by X-ray diffraction, SEM, EDX, X-ray and optical spectroscopy. It is shown that Yb3+ ions are distributed between C-type Yb2O3 sesquioxide crystals and ZnO grain boundaries. The Yb3+ doping of ZnO ceramics enhances the near-band-edge emission of zinc oxide. ZnO:Yb optical ceramics are promising for optoelectronic applications. © 2021 Institute of Physics Publishing. All rights reserved.
