Description and Uses

There are few uses for terbium. However, terbium can be used as an activator for greenphosphor in TV tubes, and some of its compounds are used to produce laser lights. It is alsoused to “dope” (coat) some forms of solid-state instruments, as a stabilizer in fuel cells so thatthey can operate at high temperatures, and as a metal for control rods in nuclear reactors.
