Effect of host polymer blends to phosphorescence emission

Abstract

Thin film poly (N-vinylcarbazole) blend with poly(vinylidene fluoride-co-hexafluoropropene)
(PVDF-HfP) and polyvinylpyrrolidone (PVP) contain 5% weight ratio of Europium (III)
Tris(dibenzoylmethane) mono(5-amino-1,10-phenanthroline) was prepared by using doctor blade technique on the spectrosil substrate. Each polymer was blended with the same ratio composition. The influences of host polymer composition to the phosphorescence emission were observed under pulsed UV excitation source of Xenon lamp. The results shows that there were changing in the phosphorescence emission and life time with difference host polymer. The explanation of phosphorescence emission has been supported by ZINDO calculation.
