摘要

With a specially designed composition, highly transparent Yb3+/Er3+-doped fluorosilicate glass ceramic (GC) containing KMnF3 perovskite nanocrystals (NCs) is obtained for the first time. The rare-earth ions are preferentially accumulated in regions embedded with KMnF3 NCs; as a result, a remarkably enhanced (by an order of magnitude) single-band red upconversion luminescence (UCL) is achieved. Absolute quantum efficiency of the red UCL, which cannot be measured in previous GCs owing to insufficiency, reaches as high as 0.10% +/- 0.02% in the GC sample reported in this Letter. This value is even higher than that of the well-known multiband emitting beta-NaYF:Er3+/Yb3+ NCs and widely recognized GCs containing NaYF4:Yb3+/Er3+NCs. (C) 2019 Optical Society of America
