Hello Sriram,

If you intend to have nanostructures as a target, I'd tend to say no on
a general basis.

General-purpose Monte Carlo codes for the simulation of radiation
transport cannot ordinarily account for what happens at the nanoscale,
since several underlying assumptions/approaches are no longer
applicable: the material is no longer homogeneous and isotropic, the
description of the electronic stopping of charged projectiles would have
to account for all sorts of plasmonic excitations in nanostructures,
etc.

Having said that, if, in spite of being nanostructured, the material
(layer?) is reasonably thick and if you happen to have an effective idea
of what the scintillation spectrum looks like, you may want to look into
chapter 12} of the manual, where there is an example showing how to
generate and transport optical photons, but beware that considerable
user input is required (mostly the main spectral features/lines of the
scintillation spectrum and the material optical responses). This could
give you a general idea of what's going on.

Note that my experience with optical photons is limited, so more
experienced people may want to correct/expand/delimit.

With kind regards,

Cesc
