Synthesis, characterization and properties of Ln(Ti0.8Sn0.2)TaO6 (Ln = Nd, Sm) microwave ceramics
چکیده انگلیسی

The Ln(Ti0.8Sn0.2)TaO6 (Ln = Nd, Sm) ceramics are prepared through the solid-state ceramic route. The structure of the materials is studied using X-ray diffraction and Raman spectral analysis. The microstructure is analyzed using scanning electron microscopy and the elemental composition by energy dispersive spectrometry. The dielectric properties in the radio as well as in the microwave frequencies are studied. The photoluminescence property of the samples is also analyzed. The materials have dielectric constants 32.3 and 31.1, temperature coefficient of resonant frequency +1.5 ppm/K and −6 ppm/K and high quality factor and hence suitable for the fabrication of devices in microwave communication. Moreover, the compounds are useful in the field of optoelectronics since they produce intense emission lines in the visible region.
