A series of novel red-emitting phosphors of Y2 - 2xMgTiO6 ∶2xEu3 + (YMT∶2xEu3 + ,0≤x≤0. 11) were synthesized by sol-gel method. Phase purity was examined by X-ray diffractometer (XRD) and the results show that the obtained YMT∶Eu3 + phosphors crystallize in the monoclinic space group P21 / n and no other peaks are observed. The SEM images show that the obtained particles exhibit the non-uniform shapes with an average size of 2 μm. The photoluminescence spectrum under the excitation of 264 nm reveals four narrow bands at 591, 619, 657 and 698 nm, which correspond to the 5D0→7F1 , 5D0→7F2 , 5D0→7F3 and 5D0→7 F4 transitions of Eu3 + , respectively. The energy transfer mechanism among Eu3 + ions is identified as dipole-dipole (d-d) interactions. The phosphor of YMT∶0. 14Eu3 + exhibits a chromaticity coordinates of (0. 645, 0. 332), which is close to the standard red color coordinates (0. 67, 0. 33). The temperature-dependent PL spectra were analyzed, and the calculated activation energy indicates the acceptable thermal stability of the phosphor. Hence, the red-emitting phosphors of YMT∶Eu3 + can be potentially applied to LED.
