Luminescent polymer electrolyte composites composed of silica coated Y₂O₃:Eu in polyethylene glycol (PEG) matrix has been produced by initially synthesizing silica coated Y₂O₃:Eu and mixing with polyethylene glycol in a lithium salt solution. High luminescence intensity at round 600 nm contributed by electron transitions in Eu³⁺ (⁵D₀ ® ⁷F₀, ⁵D₀ ® ⁷F₁, and ⁵D₀ ® ⁷F₃ transitions) were observed. The measured electrical conductivity was comparable to that reported for polymer electrolyte composites prepared using passive fillers (non luminescent). This approach is therefore promising for production of high intensity luminescent polymer electrolyte composites for use in development of hybrid battery/display.
