Abstract

The present invention discloses a tunable fluorescent gold nanocluster. The tunable fluorescent gold nanocluster is formed by mixing gold trichloride (AuCl3) with toluene solvent without reductant. The tunable fluorescent gold nanocluster emits blue fluorescence that can be red shifted through ultrasonic vibration. The spectral region of the tunable fluorescent gold nanocluster is from 400 nm to 550 nm.
