Herein, we report a novel positively charged photoluminescent Au–Ag bimetallic nanocluster synthesized using 11-mercaptoundecyl-N,N,N-trimethylammonium bromide as the capping ligand by means of “green” double-target sputtering method on a biocompatible polymer matrix. The photoluminescent Au–Ag bimetallic cluster showed emission tunability from blue to near infrared (NIR) regions with respect to change in the composition.
It can be used for bioimaging, sensing, and therapy.
