Stern-Volmer Quenching of Conjugated Polymers: A Study of Fluorophore Concentration
Abstract
The purpose of this thesis is to re-examine the independence of Stern Volmer constants on the fluorophore concentration. Conventional theory suggests that Stern-Volmer constants are independent of fluorophore concentration. Using PPEs as fluorophore, the Stern-Volmer constants were obtained for different PPE concentrations quenched with TbCl3. Stern-Volmer constants increased with decreasing PPE concentration.
