在仅油胺存在的情况下，通过热分解成功合成了共掺杂Gd³⁺、Yb³⁺和Er³⁺（或Tm³⁺）的小于10 nm的六方相NaLuF₄基纳米晶体。小于10 nm的β - NaLuF₄：24 mol% Gd³⁺，20 mol% Yb³⁺，1 mol% Tm³⁺纳米晶体在980 nm连续波激发下显示出明亮的上转换发光（UCL），量子产率为0.47 ± 0.06%。此外，通过使用β - NaLuF₄：Gd³⁺，Yb³⁺，Tm³⁺纳米晶体作为发光标记，……的检测限（最后一句不完整，未翻译最后一个词后面的内容）
By thermal decomposition in the presence only of oleylamine, sub-10 nm hexagonal NaLuF4-based nanocrystals codoped with Gd3+, Yb3+, and Er3+ (or Tm3+) have been successfully synthesized. Sub-10 nm beta-NaLuF4: 24 mol % Gd3+, 20 mol % Yb3+, 1 mol % Tm3+ nanocrystals display bright upconversion luminescence (UCL) with a quantum yield of 0.47 +/- 0.06% under continuous-wave excitation at 980 nm. Furthermore, through the use of beta-NaLuF4: Gd3+,Yb3+,Tm3+ nanocrystals as a luminescent label, the detection limit of
