This material shows a blue fluorescence which rapidly turns to green persistent phosphorescence with a lifetime of nearly 1 s. Time-dependent density functional theory calculations revealed that electronic transitions arising from both first excited singlet and triplet states involving ligand-centered and ligand-to-metal charge-transfer mechanisms are responsible for such behavior. 2017-03-06 20:43:35 polymer phosphorescence Time-dependent density theory calculations lifetime ligand-centered Photoluminescent Emission coordination Aminonicotinate Theoretical Study Cadmium Coordination Polymer material emission singlet cadmium triplet states ligand-to-metal charge-transfer mechanisms CP Experimental Second-Timescale fluorescence transition
