We report the distinctive photophysical properties of a Cu5-core metal cluster that presents, both in solution and in the solid, temperature dependent fluorescent quantum yield and excited state lifetime in the range between -45 and +80 °C. It allows for an unprecedented accuracy in temperature determination by fluorescence measurements, making it suitable for applications in nanosized environments, e.g. in biology and (nano)materials research.

Abstract

We report the distinctive photophysical properties of a Cu5-core metal cluster that presents, both in solution and in the solid, temperature dependent fluorescent quantum yield and excited state lifetime in the range between -45 and +80 °C. It allows for an unprecedented accuracy in temperature determination by fluorescence measurements, making it suitable for applications in nanosized environments, e.g. in biology and (nano)materials research.
