Question Wavelength range of material properties and number of Cerenkov photons

Hello,

My simulation of scintillator both includes Cerenkov and Scintillation process. The absorption and re-emission property of scintillator is also considered.

So, if I enlarge the wavelength range of material properties and give the corresponding refractive indices, geant4 will produce more Cerenkov photons, and then these UV photons will be shifted to the photons which is sensitive to the detector by the process of absorption and re-emission of scintillator.

Therefore, I'm confused that what is the proper wavelength range or photon momentum range for the physical situation? In the User Manual, optical photon is defined as photons wich wavelength is start from 10nm. The simulation results of including Cerenkov, Scintillation and absorption-reemisson which start from 10nm and 200nm are different very much.

Thanks! Regards, Weili
