Synthesis and Luminescence Properties of High-Purity Red-Light-Emitting Eu3+ -Doped NaZr2(PO4)3 Phosphor

This article reports the successful synthesis of high-purity NaZr2(PO4):Eu3+(0.5 mol.%-5 mol.%) phosphate phosphor by solution combustion synthesis which emits in the reddish region. The x-ray diffraction, Raman spectroscopy, x-ray photoelectron spectroscopy, photoluminescence spectroscopy, and diffuse reflectance spectroscopy measurements have all been used to analyze the synthesized phosphor's structural, vibrational, elemental composition, electronic, and optical characteristics in detail. Due to the preponderance of the magnetic dipole transition of the Eu3+ ions, the synthesized phosphors illuminated at the near ultraviolet light indicated the emission in the visible area. The phosphor's computed photometric characteristics indicated that the emission is in the reddish region with a high color purity of 94%. These findings demonstrated that the phosphor might work well in a variety of optoelectronic devices, including phosphor-converted whitelight-emitting diodes.
