Table of Contents EntryCopper and gold complexes stabilized by cyclic (alkyl)(amino)carbene ligands ( R L)MX, where X = halide, pseudo-halide, amide or aryloxide represent a large class of photoluminescent materials, with emission lifetimes ranging from nanosecond to microsecond regimes.

Simple carbene complexes of copper halides give photoluminescence quantum yields of up to 96%, with sub-nanosecond emission lifetimes.
