Novel deep red phosphor Li 2 MgGeO 4: Mn 4+ 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 Mn 4+ ion and the PLE spectra shows broad band peaking at ~ 323 within the range 220–550 nm owing to the 4A2 → 4T1 transitions of Mn 4+ ion. The optimum Mn 4+ doping concentration is about 0.4 mol.%. The luminous mechanism is explained by Tanabe–Sugano diagram of Mn 4+ ion. The results indicate that red phosphor Li 2 MgGeO 4: Mn 4+ is a beneficial phosphor for use in white light-emitting-diodes (LEDs).

Ce3+-doped 0.5La2O3-2SrO-0.5Al2O3 (LSA:Ce) phosphors had been successfully synthesized using a conventional solid-state reaction method under reducing atmosphere (H2/N2 =1/5). The phase, morphologies and luminescence properties of the LSA:Ce phosphors were investigated. The emission intensity of LSA:Ce phosphors was improved by the addition of SrF2 as flux, and red shift of PL spectra peak was observed in this phosphors. Research results shown that the LSA:Ce phosphors have the potential to meet the development of white light-emitting diodes.
