Synthesis and structural characterization of Tm:Lu2O3 nanocrystals. An approach towards new laser ceramics

Nanocrystals of Tm3+ Thulium doped cubic sesquioxides, Tm:Lu2O3, with a maximum size around 30 nm have been synthesized by a modified Pechini sol–gel method. The calcination temperature for the synthesis is 1073 K. Electron microscopy was used to analyze the presence of aggregates, and the type of b...
