摘要：

The combustion technique was used to successfully prepare new Li4Zn(PO4)(2):Eu3+ orange-red phosphors. A detailed description of the crystal phase, size distribution, luminescence characteristics, and decay curves was provided. The P21(4) space group contributes to the monoclinic structure of the Li4Zn(PO4)(2):Eu3+ phosphors. The existence of pure phases of the produced phosphors was confirmed by X-Ray diffraction analysis. The intense orange-red emission light that the Li4Zn(PO4)(2):Eu3+ phosphors produce at 593 nm is attributable to the D-5(0)-> F-7(1) transitions. The placement of Eu3+ ions at various site symmetries is supported by the variation in the intensity of the electric and magnetic dipole transition. Li4Zn(PO4)(2):xEu(3+) was shown to perform best at a concentration of 0.1 mol%, which displays great color purity. All results indicate that the Li4Zn(PO4)(2):Eu3+ phosphors have potential applications in W-LEDs.
