摘要：
Red-emitting phosphors Sr2-xZnSi2O7 : Eu-x(3+) was prepared by a combustion-assisted synthesis method and an efficient red emission under near-ultraviolet (UV) was observed. The luminescence, crystallinity, and particle sizes were investigated using luminescence spectrometry, X-ray diffractometry, and field scanning electron microscopy. The emission spectrum shows that the most intense peak is located at 614 nm, which corresponds to the D-5(0) -> F-7(2) transition of Eu3+. The phosphor has two main excitation peaks located at 394 and 465 nm, which match the emission of UV and blue light-emitting diodes, respectively.
