Abstract:
A new type of hybrid cuprous halide (TPP3Cu2Br2) is reported for luminescence lifetime thermometry, featuring both extraordinary water stability and ultrahigh temperature sensitivity. This material overcomes the long-standing trade-off between sensitivity and water resistance in metal halide-based thermometers, opening up new avenues for temperature sensing in humid or aqueous environments.
