为了研究pH值对绿色荧光喷墨油墨发光性能的影响，设计了在短波紫外光激发下呈现绿色的荧光喷墨油墨配方，并制备油墨样品，使用pH值调节剂调节荧光喷墨油墨体系的pH值，探讨pH值对荧光喷墨油墨发光强度、荧光量子产率等发光性能的影响。结果表明：三乙醇胺可以在碱性范围内调节油墨的pH值，＂-3pH值从8．7到lI．20时，荧光喷墨油墨的荧光强度、荧光量子产率均呈下降趋势。碱性过强将破坏油墨体系，油墨将出现白色絮状沉淀。

This paper is to design fluorescent inks for ink-jet printing formula when it is exposured to deep ultraviolet light to display green, and a series of ink samples are prepared, pH regulator is used to regulate pH value of green fluorescent ink- jet ink system. This paper discusses the effects of pH value on luminous intensity, fluorescent quantum yield. The results indicate that triethanolamine can regulate pH value of fluorescent ink-jet ink, when pH value increases from 8.70 to 11.20, luminous intensity, fluorescent quantum yield has a decrease tendency.
