Structural properties of Co2+ ion doped calcium cadmium phosphate hydrate nanophosphor

Inorganic nanophosphor materials have captivated the worldwide attention into the field of solid-state lighting emission displays, plasma display panels, light-emitting diodes, IR quantum counters, scintillation, etc. Nanotechnology is the foremost superior in the development of phosphors with definite size and shape. Alkali and alkaline earth phosphates are promising candidates for the inorganic phosphor materials. Manufacturing of nano-inorganic materials gained much interest due to their advance lighting applications. In this work, novel Co2+ doped Calcium Cadmium Phosphate hydrate nanophosphor (CaCdPH: Co2+) was synthesized by a traditional solid-state reaction technique. The synthesized sample was characterized by Powder XRD, SEM equipped with EDX and FTIR techniques. The hexagonal phase of the prepared CaCdPH: Co2+sample was confirmed by x-ray diffraction results, and the average crystallite size was evaluated. FTIR demonstrated the formation of vibrational modes ascribed to phosphate molecules and other hydroxyl groups. The morphologies of the CaCdPH: Co2+ nanophosphor was investigated by scanning electron microscopy.
