Replication of wood into biomorphous nanocrystalline Y2O3:Eu3+ phosphor materials
Biomorphous Eu 3+ -doped Y 2 O 3 was fabricated by replication of wood templates using vacuum-assisted infiltration of a water-based sol–gel mixture and subsequent calcination at 750°C. The precursor sols were prepared from (Y 0.95 Eu 0.05 ) 2 O 3 dissolved in 10 vol% nitric acid and adding citric a...
