Room Temperature Synthesis and Properties of Pure and Gadolinium Doped Dy2O3 Nanoparticles
Pure and gadolinium doped Dy2O3 nanoparticles were prepared by a convenient, wet chemical synthesis route and the particles were subjected to thermal, structural, morphological and optical property studies. The influence of gadolinium on particle size, lattice parameter and band gap energies were investigated. Structural and optical properties of the particles elucidated that the Gd3+ ions have substituted the Dy3+ ions without changing the cubic structure of Dy2O3. The optical property studies of Gd:Dy2O3 nanoparticles showed enhanced optical absorption in UV region with respect to pure sample. The samples also exhibited room temperature PL, having a strong emission in the visible region.
