Abstract:
Y(2)O(3) nanoparticles with strong red luminescence (quantum yield about 25%) was synthesized via simple hydroxylation of yttrium nitrate using hexamethylenetetramine as an additive; the red luminescence is emitted from oxygen-related defects of pure Y(2)O(3) nanoparticles, and is tunable by altering the additive.
