The theory of the measurement of luminescent quantum yields using chemical actinometry is described. The sample's emission intensity is measured by nearly completely surrounding the sample with an actinometer solution, and the excitation intensity is directly measured with the same type of actinometer. The ratio of the measured sample emission intensity corrected for the fraction escaping through the excitation ports to the measured excitation intensity is the absolute luminescence yield. Equations, a suitable cell design, and computer calculated correction factors for different cell dimensions and optical densities are given. The absolute yield of the actinometer is not needed, only its relative response with wavelength. New quantum-flat actinometers which should greatly simplify the measurements are described.
本文描述了使用化学光量计测量发光量子产率的理论。通过用光量计溶液几乎完全包围样品来测量样品的发射强度，并用同一类型的光量计直接测量激发强度。将通过激发端口逸出的部分校正后的测量样品发射强度与测量的激发强度之比即为绝对发光产率。文中给出了方程式、合适的样品池设计以及针对不同样品池尺寸和光密度的计算机计算校正因子。不需要光量计的绝对产率，只需要其随波长的相对响应。文中还描述了新型量子平坦光量计，它应能大大简化测量。
