Low temperature effects on up-conversion emission of Er3+/Yb3+ co-doped Y2O3

Lojpur, Vesna; Nikolić, M.; Mančić, Lidija; Dramićanin, Miroslav; Milošević, Olivera (Belgrade : Agencija FORMAT, 2012)

Over the past years, Rare Earth (RE3+) ions doped materials have been attracted a great deal of interest due to the potential application for optical temperature sensors. Luminescence properties of these materials are ...

Study of Dielectric Behavior and Electrical Properties of Hematite a-Fe2O3 Doped with Zn

Nikolić, Maria Vesna; Slankamenac, Miloš; Nikolić, N.; Sekulić, D. I.; Aleksić, Obrad S.; Mitrić, Miodrag; Ivetić, Tamara; Pavlović, Vladimir B.; Nikolić, Pantelija M. (Belgrade : Serbian Ceramic Society, 2012)

The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
