Fig. 6

Photoluminescence excitation and emission spectra of a Ag17, b AuAg16, c Ag13Cu4 and d AuAg12Cu4 in DCM solution. Each inset shows the photograph of the respective cluster solution under a UV lamp at 365 nm. Solidification-induced emission enhancement of e Ag17 and f AuAg16 clusters achieved by cooling the solution to 77 K. Inset shows the respective photographs of the solution at different temperatures. Luminescence decay profiles of g Ag17, h Ag13Cu4 and AuAg12Cu4 clusters with average lifetimes. i PL intensity of AuAg12Cu4 cluster after exposure to oxygen and argon in DCM solution.
