A series of Ca2Mg0.25Al1.5Si1.25O7:Ce3+/Eu2+/Tb3+ phosphors was been prepared via a conventional high temperature solid‐state reaction and their luminescence properties were studied. The emission spectra of Ca2Mg0.25Al1.5Si1.25O7:Ce3+,Eu2+ and Ca2Mg0.25Al1.5Si1.25O7:Ce3+,Tb3+ phosphors show not only a band due to Ce3+ ions (409 nm) but also as a band due to Eu2+ (520 nm) and Tb3+ (542 nm) ions.

Ce 3+ and/or Eu 2+ activated Ca 2 Mg 0.5 AlSi 1.5 O 7 phosphors have been synthesized by high temperature solid state reaction. The luminescence of Ca 2 Mg 0.5 AlSi 1.5 O 7 :Ce 3+ , Eu 2+ is studied as potential ultraviolet light-emitting diodes (UV-LEDs). There are two emissions peaked at 409 and 525nm...
