“…We showed that doping of Ga 3+ resulted in ZnGa 2 O 4 presence along the grain boundaries [10]. Yttrium sesquioxide (Y 2 O 3 ) is interesting because it has a smaller absorption coefficient up to a wavelength of 7 μm and low emissivity [11]. Various forms of doping of Y 3+ ions with ZnO have been reported so far, such as single crystals, thin films, microspheres and quantum dots.…”

In this work, zinc oxide (ZnO) ceramics were synthesized containing 0-5wt% of cubic yttrium sesquioxide (Y 2 O 3) nanoparticles with solid state sintering technique at 1150°C. The secondary phase of Y 2 O 3 did not enter into the crystalline zinc oxide. The Y 2 O 3 acts as an inhibitor of grain growth. The absorption of the free charge carriers by the Y 2 O 3 phase influences the infrared transmissions. The minimization of the phase mismatch while transferring the electric signal caused lower losses when Y 2 O 3 was added to the zinc oxide matrices. The presence of the cubic sesquioxide at the grain boundary contributes to the interfacial polarization at lower frequencies when an alternating field is applied to the ceramics. These properties are anticipated to show a wider range of physical, optical and dielectric properties of ZnO: Y ceramics for optoelectronic applications.
