Abstract

Yttrium titanate belongs to a family of compounds called pyrochlores with significant properties such as ionic conduction, optical non-linearity and radiation tolerance that have resulted in applications thermal barrier coatings, high-permittivity dielectrics, and materials for safe disposal of actinide-containing nuclear waste, and hydrogen storage material. The application of these materials in ODS ferritic steels, photocatalytic water splitting and a more efficient host material than TiO2 for Er3+ luminescence have been evaluated. ErxY2-xTi2O7 has tremendous applications in fiber amplifiers, integrated optical devices and selective emitters for thermophotovoltaic applications. Since 1-D nanostructures are deemed to be important building blocks for future optical and optoelectronic nanodevices, we have used electrospinning methods to synthesize nanofibers and freestanding, non-woven nanofibers membranes of single phase yttrium titanate and ErxY2-xTi2O7 (Er/(Ti+Er) at. ratio= 0 -15 %) with diameters less than 150 nm and have characterized the physical, thermal and optical properties of these nanofibers.
