摘要: Abstract In this paper, an Er(III) complex of Er(DBM)3IPD, where DBM = 1,3-diphenyl-propane-1,3-dione and IPD = 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)-N,N-diphenylaniline, is synthesized doped into poly(vinylpyrrolidone) submicron fibers through electrospinning technique. The crystal structure morphology are investigated in detail. composite exhibit smooth uniform on the substrate, with average diameter ∼1.4 μm. Photophysical data suggest that DBM ligand sensitizes center efficiently provides optimal condition for radiative decay, low temperature can enhance emission intensity by suppressing quenching effect. It found photostability largely improved compared pure complex.
