Luminescent Polymer Electrolyte Composites Using Silica Coated-Y2O3:Eu as Fillers

Luminescent polymer electrolyte composites composed of silica coated Y 2 O 3 :Eu in polyethylene glycol (PEG) matrix has been produced by initially synthesizing silica coated Y 2 O 3 :Eu and mixing with polyethylene glycol in a lithium salt solution. High luminescence intensity at round 600 nm contributed by electron transitions in Eu 3+ ( 5 D 0 → 7 F 0 , 5 D 0 → 7 F 1 , and 5 D 0 → 7 F 3 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.
