Effects of Sr2+ substitution on photoluminescence characteristics of Ba1−x−ySryZrSi3O9:xEu2+ phosphors
In this work, single-phase Ba1−x−ySryZrSi3O9:xEu2+ phosphors were synthesized via the solid-state reaction method. The crystal structure and luminescence properties were investigated using X-ray diffraction and photoluminescence measurements, respectively. An increase of the dopant Sr2+ increased th...

| description | In this work, single-phase Ba1−x−ySryZrSi3O9:xEu2+ phosphors were synthesized via the solid-state reaction method. The crystal structure and luminescence properties were investigated using X-ray diffraction and photoluminescence measurements, respectively. An increase of the dopant Sr2+ increased the emission intensity of the phosphors. The peak intensity of the samples was at y = 0.4 under near-ultraviolet light excitation (397 nm). The wavelength of the emission peaks red-shifts slightly from 477 to 483 nm due to the splitting of the 5d energy level. Sr2+ ions have a smaller ionic radius than that of Ba2+ ions, and thus the dopant changes the crystal structure, improving the energy transfer efficiency between luminescence centers. More Eu2+ solid solubility was found in Ba0.6−xSr0.4ZrSi3O9:xEu2+ phosphors (10 mol. %) than in the host BaZrSi3O9 (6 mol. %), which enhanced the emission intensity. In addition, the thermal reliability of the phosphors was studied. |
