Synthesis of Luminescent Ink from Europium-Doped Y2O3 Dispersed in Polyvinyl Alcohol Solution
Figure 7
Photoluminescence spectra of Y2O3:Eu powder prepared at heating temperature of 1000 oC containing different Eu concentrations: (top to bottom) 3% mol/mol, 4% mol/mol, 5% mol/mol, and 7% mol/mol. In measurements, the samples were excited using a UV of 250 nm in wavelength.
