Paper Abstract

High-precision measurement for fluorescence quantum efficiency of solid materials has been a very cumbersome and complex process. In recent years, though many scholars have done a lot of studies, the relative and simplified measurement are mainly been emphasised on, and it is very difficult to obtain the accurate measurement uncertainty. Refering to NRC, on the basis of the little appropriate transformation on commercial instruments, this paper introduces the absolute quantum efficiency measurement for solid materials, based on double monochromator method. Currently, the measuring wavelength covers 250-800nm, the uncertainty of quantum efficiency is about 5%(k=2) .
