This document specifies a substitution measurement method for the use of commercially available measurement equipment such as a fluorescence spectrophotometer or a spectroradiometer equipped with a monochromatic light source as incident light to measure internal quantum efficiency, external quantum efficiency and absorptance of ceramic phosphor powders, which are used in white light-emitting diodes (LEDs) and emit visible light when excited by UV or blue light, comparing to reference materials whose quantum efficiencies and absorptance have been determined in accordance with ISO 23946 prior to the substitution measurement.
