Problems solved by technology

However, a large number of studies have found that after the organic ligands with good luminescent properties are coordinated with metal ions, the transition energy transfer efficiency is low when the charge is transferred to the central metal ion, resulting in energy loss. The weakening of fluorescence intensity affects the luminescent properties of fluorescent materials to a certain extent.
