title: Reversible modulation of gold nanoclusters photoluminescence based on electrochromic poly(methylene blue).
abstract: Reversible photoluminescence (PL) switches based on a complex of gold nanoclusters and electrochromic poly(methylene blue) (PMB) were realized. The gold nanoclusters PL of hybrid device can be modulated reversibly under electrochemical stimulation. Such an electrochromic device presents several advantages, such as large fluorescence contrast under reduction and oxidation potentials, good reversibility and excellent long-time stability. This simple protocol is anticipated to offer important hints for other nanoclusters and electrochromic materials in the field of photoelectric devices.
