The book covers the fundamental concept of nanomaterials followed by the development of a versatile synthetic methodology which can be used for the synthesis of nanocrystalline ceramic powders of verity of metal oxide systems. Substitutions of different suitable metal ions at both A and B sites in ABO3 type nanocrystalline lead-free perovskite materials improve the polarization of the materials and result in diffuse phase transitions.These are useful properties for room temperature and wide temperature-range ferroelectric applications. Nanosized oxides particles helped to achieve better...

This book attempts to establish a versatile and technically simple chemical synthesis technique through the successful preparation of nanocrystalline powders of ZnGa2O4 and Cr3+ doped ZnGa2O4 for phosphor applications. In the developed synthetic method, pyrolysis of aqueous based precursor solution and triethanolamine (TEA) occurs. The precursor solution comprises of water soluble metal ion ligand complexes of the desired metal ions. TEA is used as a chelating agent for obtaining the water soluble metal-ion ligand complexes. The as synthesized powders as well as the powders calcined at their...
