Structural features and distribution coefficients of Pr 3+ , Y 3+ and Lu 3+ ions in LiY 1−x Lu x F 4 mixture crystals

Thermal Stability of LiRF4 (R = Gd, Tb) Compounds

“…At present, this family of crystals is one of the most demanded classes of solid-state laser materials. [10][11][12][13][14][15][16][17][18] Activated LiYF 4 crystals show efficient lasing in various spectral ranges. These materials are among most promising ones associated with progress in photonics, quantum computers, and quantum communications.…”

“…For example, in NaF-RF 3 systems, phases of variable composition are formed in 45-63 mol% RF 3 concentration range; and KRF 4 , RbRF 4 (R = La-Sm) and CsRF 4 (R = La-Nd) compounds, crystallize in other structural types (e.g., orthorhombic KCeF 4 , SSG Pnma, and trigonal KErF 4 , SSG P3 1 ). [9] The LiRF 4 compounds have been produced not only as bulk single crystals, [10][11][12][13][14][15][16][17][18] but also as films, [19] optical fibers, [20] and eutectic composites. [21] The LiRF 4 nanomaterials have been actively researched in recent years, both as powders [22][23][24] and as glass ceramics, [25] specifically for biomedical applications.…”
