The invention discloses a fluorescence probe for detecting a silver ion, and provides a preparation method and application thereof at the same time. The fluorescence probe can quickly respond and high-selectively detect the silver ion. The fluorescence probe for detecting the silver ion provided by the invention has a structure as shown in a formula 1. The probe provided by the invention can selectively react with the silver ion so as to produce fluorescence-emission red shift. The reaction is not interfered by other metal ions, a fluorescence-emission peak change can be produced within a short time, and the wave length of the fluorescence-emission peak red shift is in linear correlation with the concentration of the silver ion. The fluorescence probe provided by the invention only carriesout fluorescence reaction with the silver ion instead of other metal ions, so that the fluorescence probe has better selectivity and specificity.
