Effect of Solvent on the Luminescent Property of the Fluorescent Inkjet Ink

Fluorescent inkjet ink is composed of solvent,resin,phosphor,assistant etc,and solvent is one of the main components of the fluorescent inkjet ink,which has an important effect on the luminescent property.In order to discuss the effect of solvent on the luminescent property of fluorescent inkjet ink,the fluorescent inkjet ink samples were prepared with different solvents,the fluorescence intensity was tested,the fluorescence quantum yield was calculated and fluorescent lifetime was measured.The results shows that the polarity of the solvents has an important influence on the fluorescence spectrum and the fluorescence quantum yield,and the polarity of the solvents has less impact on the fluorescence lifetime. Additionally,The surface tension and viscosity of the solvent affect that of ink directly when the other components are fixed.
