Measurement Against a Standard in the Solid State

Bril [45] showed that the diffuse reflectance R and the integrated emission spectmm / for both sample and standard can be used to calculate the emission efficiency of the solid sample with Equation 2.11. 

The diffuse reflectance can be determined with the fluorimeter by scanning the emission monochromator through the excitation range and calibrating with the diffuse reflectance of
