Intra-cluster energy transfer editing in a dual-emitting system to tap into lifetime thermometry.

The impact of composition control and energy transfer on luminescence thermometry was investigated in a Tb III /Eu III dual-emitting molecular cluster-aggregate, known as {Ln 20 }. The study of lifetime dynamics sheds new light on how one can take advantage of rational planning to enhance thermometric performance and gaining insights into intriguing optical properties.
