A study of the properties of polycrystalline fluorite-type NaY1-x-yYbxEryF4 solid solutions demonstrated that NaY0.87Yb0.10Er0.03F4 and NaY0.885Yb0.1Er0.015F4 samples produced up-conversion luminescence with 3.35% and 3.62% quantum yields, which were higher than quantum yields of the other NaY1-x-yYbxEryF4 samples. NaY1-x-yYbxEryF4 specimens were prepared by co-precipitation from aqueous solutions by drop-wise addition of rare earth nitrate solutions to aqueous sodium fluoride.

Keywords: fluorides, nanopowders, sodium, yttrium, up-conversion luminescence, quantum yield.

  1. naturally like your web site but you have to check the spelling on several of your posts. A number of them are rife with spelling problems and I find it very bothersome to tell the truth nevertheless I’ll definitely come back again.
