Optical Oxygen Sensing Material: Terbium(III) Complex Adsorbed Thin Film

A new optical oxygen sensor based on the luminescence intensity change of a terbium(III) complex, tris(acethylacetonato)(1,10-phenanthroline)terbium(III) complex, ([Tb(acac)3(phen)]), adsorbed thin film onto an alumina plate, was developed. The luminescence peak positions of [Tb(acac)3(phen)] film were observed at 490, 546, 590 and 620 nm. The luminescence intensities of [Tb(acac)3(phen)] in the film decreased with increasing the oxygen concentration, indicating that the film can be used as an optical oxygen sensing device based on luminescence quenching by oxygen. The ratio I0/I100 (I0 and I100 represent the detected luminescence intensities from the film exposed to 100% argon and 100% oxygen, respectively) values of [Tb(acac)3(phen)] film are estimated to be 2.66 (490 nm), 2.68 (546 nm), 2.67 (590 nm) and 2.66 (620 nm), respectively. [Tb(acac)3(phen)] film obeyed a Stern–Volmer plot with a multi-site model and possessed good operational stability. The response times of the [Tb(acac)3(phen)] film were 7....
