LiSr 3 SiO 4 Cl 3 —A novel host lattice for Eu 2+ -activated luminescent materials

Lanthanide-doped Na2MgScF7 exhibiting downshifting and upconversion emissions for multicolor anti-counterfeiting

“…Therefore, a suitable host material is of critical importance to design a luminescent material. [24][25][26] Host crystals can be divided into fluorides, oxides, sulfides, and so on. Among them, fluorides are considered to be excellent hosts for UC luminescence owing to their low phonon energy, which alleviates the non-radiative relaxation to achieve high UC efficiency.…”

Co-doped long persistent luminescence materials LiSr3SiO4Cl3:Eu2+,Ln3+ (Ln = Dy, Ho, Er): construction and verification of VRBE and HRBE scheme and their multifunctional applications

“…Due to their unique mechanism of photoelectron storage and release, LPL materials offer unique energy storage properties and an ultra-long emission lifetime, [1][2][3] playing an indispensable role in various fields, such as biological imaging, [4][5][6] information storage, 7,8 and anti-counterfeiting. [9][10][11][12] In recent years, from the tuning of emission bands and decay times to applications of known LPL phosphors, these topics have caught the eye of many researchers and great progress has been made.…”
