Li M, Yang DP, Wang X, Lu J, Cui D - Nanoscale Res Lett (2013)

Bottom Line: A simple and cost-effective method to synthesize the luminescent noble metal clusters (Au and Pt) in chicken egg white aqueous solution at room temperature is reported.The red-emitting Au cluster is used as fluorescent probe for sensitive detection of H2O2.

Figure 1: Photographs of luminescent metal clusters in the form of solution and solid states. Under natural light and UV irradiation (λ = 365 nm).

Mentions: The photographs of as-prepared products (left: solution form, right: solid form) are shown in Figure 1. Under visible light, the solution colors (Au with three increasing concentrations and Pt) are colorless, pale yellow, deep brown, and pale green, respectively, as shown at the upper left of Figure 1. Correspondingly, under UV light (365 nm), the intense luminescences from them (under a 365-nm UV light) are also observable by naked eyes at the bottom left. Meanwhile, the solid-state luminescences are shown in the right part. Clearly, both forms indicate strong luminescence under UV light.
