F. Tao et al., SYNTHESIS AND LUMINESCENCE CHARACTERISTICS OF LIMGALF6-LN(3+) (LN = CE, EU, TB), Crystal research and technology, 32(6), 1997, pp. 849-855
By solid state reaction, LiMgAlF6 and LiMgAlF6:Ln(3+) are synthetized
with the ratio 120/100/110 of LiF/MgF2/AlF3, at 1008 K, in high-purity
Ar stream. Their crystal structure which belongs to hexagonal system
are determined by X-Ray-Diffraction (XRD). Luminescence characteristic
s of Ce3+, Eu3+, Tb3+ and sensitization of Ce3+ to Tb3+ in LiMgAlF6 ar
e studied. It is shown that the sensitization of Ce3+ to Tb3+ is effic
ient and a bright green emission is observed.
