What is Creation of CsAu nanoclusters by UV‐light irradiation on CsBr:Au^–^ crystals about?
## Abstract We have investigated the optical absorption spectra of the CsBr:Au^–^ crystals irradiated with an ultraviolet (UV) light. Before the UV‐light irradiation, the absorption bands associated with the isolated Au^–^ ion (monomer) are observed in the energy region of UV. After a slight UV‐light irradiation, the absorption intensities of the monomer bands decrease and the absorption bands due to paired Au^–^ ions appear around the monomer bands. Furthermore, UV‐light irradiation on the CsBr:Au^–^ crystals brings about the appearance of several new absorption bands in the visible region. From the analogy with the aggregation of the F centers in alkali halide crystals, the new absorption bands are attributed to the aggregate centers of the Au^–^ ions. They can also be regarded as the CsAu nanocluster constructed from the Cs^+^ cations and the Au^–^ anions. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
