For example, europium allows your television to display vibrant reds; neodymium is a key ingredient in the magnets used in hybrid - vehicle motors; and yttrium is in fluorescent lightbulbs.
They produce the materials by heating a readily available precursor material, which also allows them to incorporate triply charged europium ions, Eu3 +, as «dopants» into any of the LaOBr nanocrystals.
