By solid state reaction, LiMgAlF 6 and LiMgAlF 6 : Ln 3+ are synthetized with the ratio 120/100/110 of LiF/MgF 2 /AlF 3 , at 1008 K, in high‐purity Ar stream. Their crystal structure which belongs to hexagonal system are determined by X‐Ray‐Diffraction (XRD). Luminescence characteristics of Ce 3+ , Eu 3+ , Tb 3+ and sensitization of Ce 3+ to Tb 3+ in LiMgAlF 6 are studied. It is shown that the sensitization of Ce 3+ to Tb 3+ is efficient and a bright green emission is observed.
