Abstract: A process which uses rare-earth complexes of 2,2,6,6,-tetramethyl-3,5-heptanedione for uniform incorporation of rare earths in the cores of optical fibers is demonstrated. It is a vapor-phase transport process capable of producing fibers having a rare-earth content of at least 11 wt.% and easily lends itself to incorporation of multiple rare-earth dopants.

The "rare earth" designation inaccurately portrays the likelihood of the 17 rare earth elements' natural occurrence. Rare earth elements are actually lithophile, meaning they are enriched in the Earth's crust. In fact, most rare earth elements exist in the Earth's crust in …
Rare Earth is an American soul band affiliated with Motown's Rare Earth record label (named after the band), which prospered from 1970–1972. Although not the first white band signed to Motown, Rare Earth was the first big hit-making act signed by Motown that consisted only of white members. (None of the previously signed all-white acts - The Rustix, The Dalton Boys, or The Underdogs - had ...
A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
