This is a common observation when we try to compare cathodoluminescence data of different samples. You need to normalize the data w.r.t near bandedge peak and compare the defect emission which is green luminesce in your case.

We have done this is few of our recent CL publications, which you can see my my profile.

In case you still have any doubt, please feel free to ask [email protected]

Ahmed Barhoum

absorption and emission are size and shape dependant properties, it will be better if you check variation in the size and shape of the samples.
