Abstract: (1585 Views)
In this paper, we investigate the photoluminescence of platinum octaethylporphyrin doped in polydimethylsiloxane in the presence of oxygen. Polydimethylsiloxane is a suitable matrix for platinum porphyrin in aqueous media. An increase in dissolved-oxygen concentration in water leads to depletion of photoluminescence intensity. Quenching is the result of non-radiative energy transfer from excited phosphorescent molecules to the oxygen molecules via direct collision. Thus optical spectroscopy is employed to investigate the impact of dissolved oxygen concentration on the photoluminescence intensity.
