Rare earth strontium nanocrystals can help LEDs reduce costs

According to foreign media reports, rare earth lanthanum nanocrystals may become a missing raw material for making white LEDs cheaper and more energy efficient.
The report said: "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. Expert Pan's The University of Georgia team used yttrium oxide and alumina powders to synthesize nanocrystals as raw materials because the unique properties of rare earth elements are well suited as dopants and additives with good magneto-optical properties.
