Peter,

    Hi!

    I so sorry to find that I didn't make myself clear about the question. The expected process of a photon is:

    A photon is generated in LiquidScintillator, and transported to the LiquidScintillator and Window (made of glass) interface. It reflected back or transmit through the interface. As the refrative index of window and LiquidScintillator are very closed, the photon is very likely to transmit through the interface. Because the Absortion length of glass is large, the photon is with little probability to be absorbed, instead, it travels to the window and photocathode (K2CsSb) interface. 

    Because K2CsSb is some kind of semiconductor with non-ignorable imaginary part, which, will make a great difference to the reflectivity of the interface. If the photon is not reflected, it is expected to be transimitted through and absorbed, causing the photoelectric effect.

    The problem is when I set the complex refrative index for the photocathode, the photons seems to disappeared once they get to the surface. If the imaginary part is not set, the calculated reflectivity would be smaller than the true value.

    So I'm wondering maybe there's some way to achieve the function.
