Preparation and characterization of LiAEAlF6:Eu (AE=Mg, Ca, Sr or Ba) phosphors

Sol-Gel-Synthesis of Nanoscopic Complex Metal Fluorides

“…All complex metal fluoride sols showed long-time stability and transparency even after months. These complex metal fluorides recently gained an enormous amount of interest as hosts for fluorescent materials [1,2,3,4,5,6,7] due to the suitable sizes of the ionic radii of alkaline earth cations. In addition, they exhibit high ionic strength, hardness, good isolation behavior, and are stable over a wide temperature range.…”

“…These complex metal fluorides are often used as host materials for a wide range of applications in the optical luminescence field. They can be applied, for instance, as laser materials, thermoluminescent detectors, or phosphors for lamps and displays [1,2,3,4,5,6,7]. Furthermore, complex fluorides are appropriated in the ceramic field because of their good physical properties like high ionic strength, piezoelectric characteristics, and nonmagnetic insulator behavior [8].…”

“…Notably, the ternary metal fluorides (CaAlF 5 , Ca 2 AlF 7 , SrAlF 5 , and Sr 2 AlF 7 ) are used as fluoroaluminate substrates due to their very good chemical stability and remarkable optical properties [9,10,11,12]. LiCaAlF 6 , LiMgAlF 6 , and LiSrAlF 6 are suitable hosts for solid-state lasers [2]. …”

Luminescence of Ce3+ in Ca0.65La0.35F2.35 host

“…In recent years, some wet chemical processes for the synthesis of OH À free fluorides have been described [9,10]. We have successfully used these methods for synthesizing various fluorides [11][12][13][14] Use of chlorides as starting material helps in preventing the hydrolysis. Hence, complex fluorides were prepared by dissolving the analytical reagent grade chlorides of the constituent metals in the stoichiometric ratios in double distilled water in a PTFE container.…”

Comparison of thermoluminescence characteristics in γ‐ray and C5+ ion beam‐irradiated LiCaAlF6:Ce phosphor

“…Ce 3+ -activated LiCaAlF 6 is a well-known phosphor with diverse applications in solid-state tunable lasers and scintillators (15)(16)(17)(18)(19). A lot of work has been done on colquirite-type LiCaAlF 6 phosphors explaining their Photoluminescence (PL), Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) properties triggered by different activator ions (20)(21)(22)(23)(24). However, no studies on ion-beam irradiated LiCaAlF 6 :Ce have been found.…”
