Question

What are the application of lanthanoids?

✓

Answer

$1.$ Lanthanoid compounds are used inside the colour television tubes and computer monitor. For example mixed oxide $(Eu, Y)_{2 }O_3$ releases an intense red colour when bombarded with high energy electrons.
$2.$ Lanthanoid ions are used as active ions in luminescent materials. $($Optoelectronic application$)$
$3. \ Nd : YAG$ laser is the most notable application. $(Nd : YAG =$ neodymium doped ytterium aluminium garnet$)$
$4.$ Erbium doped fibre amplifiers are used in optical fibre communication systems.
$5.$ Lanthanoids are used in cars, superconductors and permanent magnets.
