Nanoclusters of dicyanocuprate (I) ions doped in different alkali halide single crystals (NaCl, NaBr, and NaF) have been studied. Several emission bands are seen which are assigned to different [Cu(CN)2]- luminescent nanoclusters in the host lattices. Molecular modeling provides a theoretical prediction of how the distribution of nanoclusters varies with the host lattice. DFT calculations indicate the presence of exciplex behavior and provide a basis for the assignment of the different luminescence bands. Comparison of these nanocluster results will be made with the results for both pure bulk KCu(CN)2 and NaCu(CN)2, which exist as one dimensional cyanide bridged polymer chains.
