Preparation of Nanocrystalline Lu2O3:Eu Phosphor via a Molten Salts Route. —
The title phosphor is synthesized by decomposition of mixtures of Lu(NO3)3 and
03- 014 Eu(NO
3)3, or LuCl3 and EuCl3 in the eutectic mixture of KNO2 and NaNO2 already at
250 °C. For better purity of the final product the synthesis should be performed at
350 °C for nitrate or 475 °C for chloride precursors. The luminescence of samples
made from Lu(NO3)3 is noticeably higher compared to the products obtained from
LuCl3. — (TROJAN-PIEGZA, J.; ZYCH*, E.; J. Alloys Compd. 380 (2004) 1-2,
