| Erbium is one of the three Lanthanides named after the small Swedish town of Ytterby. The other two are terbium and ytterbium. |
| In this context, one objective of the project is the design of ytterbium doped fibre for the development of high power transversally singlemode light sources. |
| The 70th element, ytterbium, was named after the small Swedish town of Ytterby. |
| The anomalously large LCTE values for europium and ytterbium again confirm the divalent nature of those two metals. |
| The village is Ytterby and the elements are yttrium, erbium, terbium and ytterbium. |
| It is extracted from its ores by heating lanthanum metal with ytterbium oxide. |
