A highly intense yellow-emitting phosphor :, peaking at 593–611 nm was synthesized by the sol-gel method. XRD and SEM show that the samples are single phase and have irregular shape. The excitation wavelength matches well with that of the emission of the blue-light-emitting diode. The emission peaks at 593 and 611 nm are attributed to the transitions from the 5D07F1 and 5D07F2 of ions, respectively. was used as sensitizer, aiming at increasing the luminous intensity. A certain amount of and is contributed to the intensity of light emission.
