Synthesis and optimization of photoluminescence properties in potential reddish orange emitting niobate phosphor for photonic device applications.

A series of samarium ions (Sm ) activated barium sodium niobate (Ba NaNb O ) samples have been successfully synthesized via employing a solid-state reaction technique. Single phase, crystalline tetragonal Ba NaNb O were formed and the crystallite size of the prepared sample varied with doping of Sm ions. The scanning electron microscopy (SEM) images of Ba NaNb O :Sm illustrate that the particles possess a non-uniform spherical structure with some agglomeration.
