Abstract In the present study, Fex/ZrO2 (0 ≤ x ≤ 25) nanoparticles were synthesized by a facile modified Sol-Gel method. Stabilization of the tetragonal phase of ZrO2 is studied as a function of both the Fe incorporation ratios and thermal treatment. The Fe incorporation ratios are tested up to the extreme just before FeO and Fe2O3 phases are formed separately. The prepared Fex/ZrO2 nanoparticles XRD analysis depicts the formation of zirconium oxide at different Fe ratios in the nanoscale with an excellent degree of crystallinity in the tetragonal phase. The effect of thermal treatment on stabilizing the tetragonal phase of Fex/ZrO2 nanoparticles is extensively studied. The phase transition to the monoclinic phase is determined as function of Fe incorporation ratios and annealing temperatures. The optical absorbance spectra showed that the optical band gap decreased with increasing Fe ratios without the formation of doping bands which confirms the formation of Fex/ZrO2 single matrix.

In this paper, our aim was to develop the Neodymium oxide (Nd2O3) based nano composites using sol gel method. This work is mainly focused on to study the synthesis of metal composites by sol gel method. We will also observe the morphologies and dimension of neodymium oxide doped nano composites are influenced due to alteration in growth parameters such as different composition or thermal treatment. The structure of the sample prepared was studied using optical microscope. The other objective would be to investigate the synthesis of modem oxide doped nano composites.
