摘要
Abstract Photostability in solid state is one of the crucial parameters of fluorescent substances for their applications. Different factors during the fabrication processes can significantly affect their photostability. In this work, we prepared N,N′-Bis(2,6-dimethylphen-yl)-perylene-3,4,9,10-tetra-carboxy-licdiimide (DXP) films by directly spin-casting the precursor solutions of DXP in a mixed solvent (methanol and toluene). We found that the photostability and fluorescence quantum yield of DXP in the final solid films have strong correlation with the ratio between methanol and toluene in the precursor solutions. These results show the importance of the solvent used during the fabrication process and give suggestions for better routes.
