· JVASP-138891· NaTlF4

Sodium thallium fluoride (NaTlF₄) is an inorganic ceramic compound belonging to the fluoride family, which comprises ionic solids with strong metal-fluorine bonds. This material is primarily used in specialized optical and photonic applications, particularly as a host material for rare-earth ion doping in laser systems and upconversion phosphors. NaTlF₄ is notable in research contexts for its potential in infrared (IR) laser technology and fluorescence applications where its fluoride structure provides excellent optical transparency and thermal stability compared to oxide ceramics.
