Terbium Carbonate 99.99% has important role as an activator for green phosphors used in colour TV tubes, is also used in special lasers and as a dopant in solid-state devices. Terbium ‘green’ phosphors (which fluoresce a brilliant lemon-yellow) are combined with divalent Europium blue phosphors and trivalent Europium red phosphors to provide the ‘trichromatic’ lighting technology which is by far the largest consumer of the world's Terbium supply.
