Uses
Lead(II) bromide is used for developing images in photography; as inorganic filler in fire-retardant plastics; as a photopolymerization catalyst for acrylamide monomer; and as a welding flux for welding aluminum or its alloys to other metals. Lead bromide is used for developing images in photography; as inorganic filler in fire-retardant plastics; as a photopolymerization catalyst for acrylamide monomer; and as a welding flux for welding aluminum or its alloys to other metals. It is used in the field of antirust, pigment and photograph. The molten lead(II) bromide acts as an electrolyte. Lead(II) bromide provides a high concentration of lead(II) ions and bromide ions to carry the current during the electrolysis process. The rare-earth-doped alkali-lead bromide crystals (potassium lead bromide (or) KPB; rubidium lead bromide or RPB) emerge as promising new low-phonon-energy host materials for mid-IR applications and are useful for solid state lasers. Hybrid organic/lead halide perovskites are promising materials for solar cell fabrication. Lead(II) bromide (PbBr2) can be used in the fabrication of nanoscale quasi-2D layered perovskites, which are potentially utilized as light-emitting materials. It can also be used for the synthesis of deep blue fluorescent lead bromide perovskite microdisks. These microdisks can be used as direct bandgap semiconductors for light-emitting diodes (LEDs).
