Abstract
A new phosphor, (Gd1.54Zn0.46)O3−δ:Eu0.063+, with a photoluminescent quantum efficiency of ≈86% and a superior color chromaticity (x=0.656, y=0.344) compared to the state of art red phosphor Y2O3:Eu3+ was identified using the combinatorial thin film synthesis method. This phosphor may replace Y2O3:Eu3+ in display applications where a more saturated red phosphor is preferred.Keywords
