· Pr4 Br10

Pr₄Br₁₀ is a rare-earth bromine compound belonging to the lanthanide halide family, composed of praseodymium and bromine in a 4:10 stoichiometric ratio. This is an experimental/research-phase material studied primarily for its potential in optoelectronic and photonic applications, leveraging praseodymium's luminescent properties in the visible and near-infrared spectrum. Research interest centers on its use in scintillators, optical fibers, and solid-state laser hosts, though industrial deployment remains limited compared to more established rare-earth compounds.
