چکیده
Luminescent EuIII coordination polymer with amorphous transformation and thermo-sensing abilities under higher temperature, [Eu(hfa)3(tppa)n]m (hfa: hexafluoroacetylacetonate, tppa: tri-diphenylphosphoryl-4,4,4-triphenylamine) is reported. The glass transition decomposition temperatures are found to be 142 °C 270 °C, respectively. intrinsic emission quantum yield Φ4f−4f of was estimated 69 % in solid state. shows effective decrease the lifetime upon increasing temperature from 320 400 K. temperature-depended caused by back energy transfer emitting level ion (5D0) LLCT band (tppa ligand hfa ligand) [Eu(hfa)3(tppa)n]m. Thermo-sensitive lanthanide luminophore stable formation (>100 °C) useful for surface detection field high-speed wind tunnel experiments such as aircraft automobile designs.

متن کاملFluorescence enhancement by microphase separation-induced chain extension of Eu coordination polymers: phenomenon and analysis
In this paper, we report on the fluorescence enhancement of Eu coordination complexes in dilute solutions through electrostatic complex micelle formation with an oppositely charged block polyelectrolyte. The coordination complexes alone are oligomeric structures which have many ends where partially coordinated europium is exposed to water. In the presence of oppositely charged polyelectrolytes,...
