According to foreign media reports, rare earth lanthanum nanocrystals may become a missing raw material for making white LEDs cheaper and more energy efficient.

It is reported that scientist Budai is working with a group of scientists at the University of Georgia and the Oak Ridge and Argonne National Laboratory to study a new set of crystals that produce the correct blend of white LEDs and other uses.

The team used cerium oxide and aluminum oxide powders to synthesize nanocrystals as raw materials, because the unique properties of rare earth elements are very suitable as dopants and additives, and have good magneto-optical properties.
