Compared with the maximum emission of crystal 1, crystal 2 appears spectral bands redshift(46nm), the emission peak of crystal 2 is obviously enhanced, which maybe attributed to that all the coordination atoms of crystal 2 participate in the coordination reaction, cause the extent increase of ligand-to-metal charge transfer (LMCT) , and lead to spectral bands redshift. At the same time, crystal 2 has 3D spatial structure making its rigid further increase, which weaken the radiation vibration quenches of fluorescence and increase the luminescence intensity . |
