High thermal stability pyroxene type CaScAlSiO6:Tb3+/Sm3+ ceramics with excellent cryogenic optical thermometry performance

Synthesis and photoluminescence properties of a novel green‐emitting LiYGeO4:Tb3+ long afterglow phosphor

“…[ 13 ] The NaCa 2 GeO 4 F:Tb 3+ phosphor made by Pengxiang Pei proved its potential value in multicolour anticounterfeiting. [ 14 ] Su K described CaScAlSiO 6 :Tb 3+ /Sm 3+ ceramics with excellent cryogenic optical thermometry performance [ 15 ] and the Eu 2+ /Tb 3+ co‐doped phosphor has potential applications in cryogenic thermometric sensing. [ 16 ] Furthermore, Liu H developed a new strategy for realizing ratiometric optical thermometry via efficient Tb 3+ –Mn 2+ energy transfer in the phosphor Ca 9 Tb(PO 4 ) 5 (SiO 4 )F 2 .…”

Structure, luminescence properties and energy transfer of terbium and samarium co-doped barium based apatite phosphor with tunable emission colour

“…The ion pairs Tb 3+ →Sm 3+ can create a light of multiple colours, which would be beneficial to meet our requirements. When used in phosphor activation processes, samarium is capable of producing red light, in contrast, terbium may be employed as a phosphor sensitizer to produce green light [ 11 , 12 , 13 ]. Apatite compound is frequently selected as the host owing to its great chemical stability that is unaltered by the fluctuating crystal field environment.…”
