Functional novel polymer electrolytes containing europium picrate

Abstract

Novel polymer electrolytes based on either di-ureasil ormolytes or gelatin and containing europium picrate [Eu(pic)(3)] were prepared, characterised and compared by conductivity measurements, thermal analysis and electrochemical stability, X-ray diffraction, scanning electron microscopy and photoluminescence spectroscopies. Small electrochromic devices (ECDs) with gelatin-europium salt optimised composition were assembled and characterised. The obtained results confirmed that these materials may perform as satisfactory multifunctional component layers in the field of ECD based devices.
