| 摘 要： | 荧光增白剂吸收近紫外光,发射可见光,使织物增白.通过对荧光增白剂的溶液进行一系列光学测定与分析.得出:荧光物质本身具有固定的光吸收区和荧光发射区,并有固定的最大激发波长和最大发射波长;一定浓度范围内荧光物质的吸收与浓度成正比关系;荧光量子效率不随激发光波长而变化.

| Abstract: | Fluorescent brightening agents (FBA) absorb light - energy in the near - ultraviolet region of the spectrum and emit light - energy in the visible - light region so that they can enhance the whiteness and brightness of cloths. By carrying out a series of experiments and analyses, following results have been obtained. FBA have a fixed absorption and emission region in which both have their maximum energy wavelengths. In a certain range of concentration, the energy of absorption are positive proportional to the concentration of FBA. Fluorescent quantum efficiency has nothing to do with the wavelength of exciting light. |
