蓝色荧光喷墨油墨的荧光光谱与荧光量子产率

测试了荧光喷墨油墨的激发光谱与荧光光谱，用相对测量法测定了荧光喷墨油墨在不同激发波长下的荧光量子产率，探讨了溶剂种类以及树脂含量对荧光喷墨油墨量子产率的影响。结果表明，溶剂极性和树脂含量对荧光喷墨油墨的荧光量子产率均有较大影响，在二丙二醇甲醚中，荧光量子产率最大为O．96；与树脂质量分数为8％时相比，树脂质量分数为10％时的荧光量子产率较大。

Fluorescence Spectra and Fluorescence Quantum Yield of Fluorescent Inkjet Ink

Fluorescence quantum yield is one of the most important parameters of fluorescent materials. The fluorescence excitation spectra and fluorescence spectra have been tested, and the fluorescence quantum yields of fluorescent inkjet ink samples under different excitation wavelength have been calculated with relative measurement method. The effect of solvent types and the content of resins on the fluorescence quantum yield have been measured. The results indicate that the polarity of the solvents and the content of resins have important influence on the fluorescence quantum yield. The fluorescence quantum yield reached the maximum value 0.96 when the dipropylene glycol monomethyl ether was used as the solvent, and compared with 8%, the fluorescence quantum yield was higher when the content of resin was 10%.
