Manganese induce a strong green color in glass by forming less-colored iron(III) and slightly pink manganese(II), compensating for the residual color of the iron(III). Larger quantities of manganese are used to produce pink colored glass. Tetravalent manganese is used as an activator in red-emitting phosphors. While many compounds are known which show luminescence the majority is not used in commercial application due to low efficiency or deep red emission. However, several Mn aktivated fluorides were reported as potential red emitting phorshors for warm-white LEDs. But to this day, only KSiF:Mn is commercially available for use in warm-white LEDs. The manganese oxide
Manganese exporter manganese efflux pump. Manganese sensitivity and intracellular manganese levels significantly increased in bacteria when the "mntP" (formerly "yebN") gene, which encodes the MntP efflux pump, was deleted. While manganese is a highly important trace nutrient for organisms from bacteria to humans, acting as an important element in the defense against oxidative stress and as an enzyme cofactor, it becomes toxic when present in excess. Manganese exporter The Manganese (Mn2+) Exporter (MntP) Family (TC# 2.A.107) is a member of the Lysine Exporter (LysE) Superfamily. The MntP family is a small family whose members have been found in bacteria and archaea. MntP
