摘要：

Red-emitting phosphor InNbO4:Eu3+ was synthesized by the solid-state reaction. Its crystal structure, particle size distribution, and luminescence properties were studied. The powder X-ray diffraction pattern shows that pure InNbO4:Eu3+ was obtained. According to the spectra obtained, this phosphor can efficiently be excited with the light at wavelengths of 394 and 466 nm to emit the strong red radiation at 612 nm due to the (5) D (0)->(7) F (2) transition of Eu3+. The best results were obtained at the concentration of the Eu3+ dopant equal to 4 mol.%. The chromaticity parameters of InNbO4:0.04Eu(3+) are close to standards of the National Television Standard Committee. Thus, InNbO4:Eu3+ is a promising red-emitting phosphor for white-light emitting diodes.
