Preparation, structure and up-conversion luminescence properties of novel cryolite K₃YF₆:Er³⁺, Yb³⁺

Abstract

Single-phase up-conversion luminescent materials K3YF6:Er3+, Yb3+ with cryolite structure were obtained for the first time.

Controllable crystal form transformation and luminescence properties of up-conversion luminescent material K3Sc0.5Lu0.5F6: Er3+, Yb3+ with cryolite structure

“…B ¼ Al 3+ , Sc 3+ , Ga 3+ , In 3+ , etc. ), 23 and up-conversion luminescent ion pairs can occupy the B site easily, forming a coupled isomorphic replacement in the cryolite crystal lattice. In recent years, research on cryolite structure compound as a luminescent host material has been widely reported, such as K 3 ScF 6 : Tm 3+ , Yb 3+ , 24 K 3 YF 6 : Er 3+ , Yb 3+ 23 , K 3 LuF 6 : Tb 3+ , Eu 3+ , 25 K 3 GaF 6 : Mn 4+ , 26 Na 3 GaF 6 : Eu 3+ , 27 K 3 GdF 6 , 28 K 3 AlF 6 : Mn 4+ .…”
