Luminescence of La3F3[Si3O9]:Ce3+

Comparison of the spectroscopic behaviour of single crystals of lanthanide halides (X = Cl, Br)

“…The ground state configuration (4f 1 ) yields two levels, 2 F 5/2 and 2 F 7/2 ; the excited state configuration (5d 1 ) yields a couple of crystal-field split components. Thus, almost all the emission spectra of the Ce 3+ ion consist of a double band with maxima separated by 2000-3000 cm −1 [21][22][23]. This corresponds to the ground state splitting.…”

The VUV–vis luminescent properties of Ln3+ (Ln = Ce, Pr, Tb) in Sr0.96Na0.02Ln0.02B4O7

“…The barycenter of 4f5d levels for Ce 3+ ions in most oxide hosts are reported to be around 35 × 10 3 cm −1 [22]. This value lies in 43.4 × 10 3 cm −1 in the host SrB 4 O 7 , which is relatively higher than that in most oxide hosts.…”

The lanthanoid(III) chloride cyclo-tetrasilicates M6Cl10[Si4O12] (M=Sm, Gd–Dy): Synthesis, structure and IR investigations

“…With the smaller halide F À as derivatizing anion another rare-earth metal cyclo-oxosilicate exists; however, La 3 [13] which shows only ortho-silicate tetrahedra [13] do not only offer an interesting structural chemistry, but also amazing luminescence properties by using these compounds as host lattices (especially the La 3+ and Y 3+ compounds) for doping in small amounts of suitable lanthanoid trications such as Eu 3+ . La 3 F 3 [Si 3 O 9 ] doped with Ce 3+ has already proven to be a powerful UVluminescent material [14] and most fluoride oxosilicates look very promising in exhibiting similar properties (e.g. visible and IR-luminescent Y 3 F[Si 3 O 10 ]:M 3+ with M ¼ Nd, Eu, Tb, Dy, Er, and Yb [15]).…”
