A study of the properties of polycrystalline uorite-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-yyYbxEryF4 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 uoride.
