Abstract

Erbium triflate, Er(CF3SO3)3, salt has been dissolved in poly(ethylene glycol) (PEG400) and analysed at 295 K. The experimental optical absorption spectrum is compared to that calculated using a modified Judd–Ofelt approach. Comparable amorphous polymer–salt systems, Er(CF3SO3)3 dissolved in poly(ethylene oxide) (PEO) [EO∶Er ratios 100, 50, 28.6 and 25∶1] have been simulated at 300 K using molecular dynamics (MD) and the different MD-generated rare earth environments have been used to calculate crystal-field parameters. A variety of coordination types are found for the Er3+ ions. Agreement between the calculated and experimental spectra is quite satisfactory; discrepancies can be ascribed to inappropriate free-ion parameters and the crystal-field model used.
