A New Cubic Phase for a NaYF4 Host Matrix Offering High Upconversion Luminescence Efficiency.
A NaYF4 host matrix with a new cubic phase is fabricated to offer high upconversion luminescence efficiency. The new cubic phase is formed through a hexagonal-to-cubic phase transition by shining intense near-infrared light on lanthanide-doped hexagonal NaYF4 materials.
