Hi,

The forum and the G4 users guide for application developers describe these in good detail. See, for example,

NE102a is a polyvinyltoluene (PVT) -based plastic scintillator. It uses a primary scintillant and a secondary wavelength shifter to shift light out of the high absorption region below 400 nm. To first order, you can develop a model based on the emission spectrum of the secondary wavelength shifter. A more physical model can be found here:

There are several manufacturers of PVT scintillator. Here are two:
