| Popis: | A study of the properties of polycrystalline fluorite-type NaY 1-x-yYb xEr yF 4 solid solutions demonstrated that NaY 0.87Yb 0.10Er 0.03F 4 and NaY 0.885Yb 0.1Er 0.015F 4 samples produced up-conversion luminescence with 3.35% and 3.62% quantum yields, which were higher than quantum yields of the other NaY 1-x-yYb xEr yF 4 samples. NaY 1-x-yYb xEr yF 4 specimens were prepared by co-precipitation from aqueous solutions by drop-wise addition of rare earth nitrate solutions to aqueous sodium fluoride. |
