Luminescence Studies of Transition Metal Ion Doped CeO2 Nanophosphors

Luminescence studies of rare earth & transition metal ions by using solution combustion method. Recently there is increase in demand for the green synthesis of nanophosphors due to their nontoxic nature, use of environmentally benign precursors in the process that do not release harmful byproducts. Most of the phosphors prepared by physicochemical methods of synthesis reported usually employ organic solvents and toxic reducing agents. These chemicals are highly reactive and pose potential environmental and biological risks. With the increasing interest in elimination of hazardous chemicals, the development of environment friendly biological, biomimetic and biochemical approaches are highly desirable. Biological approaches have more advantages over physicochemical methods. Various techniques were reported to synthesize metal oxide nanostructures. Most of the commercially produced oxide phosphors involve typical process namely raw materials, blending, high temperature treatment, washing, milling, filtering, drying and sieving etc.
