Absolute up- and down-conversion luminescence efficiency in hexagonal Na(Lu/Y/Gd)F4: Yb, Er/Tm/Ho with optimized chemical composition

Up- and down-conversion luminescence efficiency of hexagonal NaYF4, NaLuF4 and NaGdF4, prepared by a novel hydrothermal method using succinic acid and codoped with Yb and Er/Tm/Ho, was investigated over a broad spectral range 350 – 1640 nm. For this synthesis method NaLuF4 matrix provided the best u...
