Highly transparent Sm2Zr2O7 ceramics with excellent dielectric performance

Dielectric ceramic is one of the most significant dielectric materials utilized as capacitors, energy storage device, and 5G resonator antenna. To better expand its application potential as optoelectronic material, this work reports the fabrication of transparent Sm2Zr2 O-7 dielectric ceramics. Single phase of the prepared samples was formed by simple solid-state reaction with high transmittance over 73%. High dielectric constant (similar to 23) and the low dielectric loss (<0.03) of Sm2Zr2O7 transparent ceramics were obtained at both the low and high frequency regions, which is twice of reported YAG and AlON transparent ceramics. Combining excellent optical property with outstanding dielectric performance, our work demonstrated that Sm2Zr2O7 transparent ceramics is potential as optoelectronic material.
