Formatted abstract
ZnGa 2O 4 nanoparticles doped with lanthanide ions (Tb 3+ and Eu 3+) were prepared at a low temperature of 120°C based on urea hydrolysis in ethylene glycol medium. X-ray diffraction studies have confirmed that strain associated with nanoparticles changes as Tb 3+ gets incorporated in the ZnGa 2O 4 lattice. Based on steady state emission and excitation studies of ZnGa 2O 4:Tb nanoparticles, it has been inferred that ZnGa 2O 4 host is characterized by a broad emission around 427 nm and there exists energy transfer between the host and Tb 3+ ions. Unlike this, for ZnGa 2O 4:Eu nanoparticles, very poor energy transfer between the host and Eu 3+ ions is observed. These nanoparticles when coated with ligands like oleic acid results in their improved dispersion in organic solvents like chloroform and dichloromethane.
