Novel deep red phosphor Li2MgGeO4:Mn4+ is synthesized by high temperature solid state reaction method in air. The strongest PL band peaking at ~ 671 nm in the range of 600–750 nm is due to the 2E → 4A2 transition of Mn4+ ion and the PLE spectra shows broad band peaking at ~ 323 within the range 220–550 nm owing to the 4A2 → 4T1 transitions of Mn4+ ion. The optimum Mn4+ doping concentration is about 0.4 mol.%. The luminous mechanism is explained by Tanabe–Sugano diagram of Mn4+ ion. The results indicate that red phosphor Li2MgGeO4:Mn4+ is a beneficial phosphor for use in white light-emitting-diodes (LEDs).
