The blue phosphor stayed generally unchanged, a silver-doped zinc sulfide. The green phosphor initially used manganese-doped zinc silicate, then evolved through silver-activated cadmium-zinc sulfide, to lower-cadmium copper-aluminium activated formula, and then to cadmium-free version of the same.
Phosphorus is also an important component in steel production, in the making of phosphor bronze, and in many other related products. [ 115 ] [ 116 ] Phosphorus is added to metallic copper during its smelting process to react with oxygen present as an impurity in copper and to produce phosphorus-containing copper ( CuOFP ) alloys with a higher ...
