荧光色料的库贝尔卡-芒克理论

在库贝尔卡-芒克理论中,没有考虑紫外光或短波可见光激发荧光色料产生荧光对总光谱反射辐亮度因子的贡献。色料激发辐射的荧光只能用光学仪器来测量,无法进行理论上的定量计算。因此无法进行荧光色料的计算机配色。本文在库贝尔卡-芒克理论基础上,运用广义量子效率概念,导出了荧光色料的总光谱反射辐亮度因子公式,得到了一些重要结论。

KUBELKA-MUNK THEORY OF FLUORESCENT COLORANTS

The fluorescent contribution to the total spectral radiance factor, which results from fluorescent colorant excited by the ultraviolet or the short-wavelength visible light, is not considered in Kubelka-Munk theory. The fluorescent power emerging from the colorant can only be measured by the optical instruments, but not be calculated quantitatively by theory. For this reason, it is impossible to make color matching in computer. In this paper, a model of transforming the excitation spectrum into the fluorescent spectrum is developed by using the concept of the generalized quantum efficiency based on Kubelka-Munk theory. A formula for calculating the total spectral reflected radiance factor of fluorescent colorants is derived, and some important conclusions are also obtained.
