摘要

We report a novel ytterbium complex [Yb(tta)(3)DFQZ] which exhibited obviously enhanced two-photon sensitized near-infrared luminescence properties of Yb3+ compared to the usually reported Yb3+ complexes, with a two-photon excitation action cross-section of 22 GM under excitation at 860 nm at 298 K. Unlike other lanthanide complexes, [Yb(tta)(3)DFQZ] under nitrogen exhibited quantum yields for the sensitized Yb3+ luminescence that increased with increasing temperature. [Yb(tta)(3)DFQZ] was dispersed in a polymer film to prepare a near-infrared-emission sensor that made it possible to conveniently detect the temperature in a range from 178 to 378 K without the influence of O-2, via a luminescence spectrum of Yb3+ in the film. This provided a promising solution to the long-standing problem that complex calculations and complicated structures are usually needed for eliminating the influence of O2 on temperature sensing with a luminescent sensor.
