Abstract

A series of Gd7O6(BO3)(PO4)2:xDy3+ phosphors are synthesized using high‐temperature solid‐phase method. The phase and spectral characteristics of phosphors are analyzed using X‐ray diffraction and spectrometer. It is found that the ratio of the light intensity corresponding to the electric dipole and magnetic dipole can regulate the color of the photoluminescence, and the optimal concentration x = 0.05 reaches 1.0834, which is very close to white light. This phenomenon is related to the symmetry of the lattice. Simultaneously, it is observed that the fluorescence decay lifetime decreases with increasing concentration. The Commission Internationale de l'Eclairage coordinates obtained from the measured color of the sample are also very close to the standard white light coordinates (0.3333, 0.3333). The results presented above suggest that Gd7O6(BO3)(PO4)2:xDy3+ is a promising candidate for the next generation of white light‐emitting diodes.
