Notes:
The luminescence properties of two low-density polyethylene samples are examined, one prepared using oxygen and the other using a benzoyl-based initiator as catalysts. The fluorescence emission from both samples is assigned to the presence of an impurity, α,β-unsaturated carbonyl of the enone type. The phosphorescence emissions, on the other hand, are different. The phosphorescence emission from the sample prepared using oxygen as an initiator is assigned to the presence of a dienone impurity chromophore, whereas the emission from the sample prepared using a benzoyl-based initiator is assigned to benzoic acid residues.
