Design and Fabrication of Some Rare Earth Doped Metal Oxide. Futuristic Green Technology of Functional Nanomaterials for Multifunctional Application

      Аннотация: Rare earth-doped metal oxide nanomaterials were produced via one of the green synthesis routes. The prepared nanocomposites are characterized to determine the structural, morphological, optical, and electrical properties. XRD is employed for the estimation of crystallite size. TEM image shows the particles are found to be in the nano range that are used for the fabrication of the nanoelectronics. SEM images depict porous, voids, and agglomeration. EDX analysis confirmed the elements present in the prepared sample. FTIR was used to identify the composition of the obtained samples. K-M plot is employed to find out the energy band gap of the prepared samples. Light emission of the PL spectra shows that samples are useful for the LED. The increases in the TL intensity with the dose rate found useful for the dosimetry. Dielectric properties and AC conductivity of all the samples were studied for the different frequency ranges. The results show that the materials have higher dielectric constant and low dielectric loss that can be used as electrical insulating material in nano packing applications. Therefore, the prepared samples are useful for multifunctional applications.
