We present photoreflectance (PR) in combination with temperature and density dependent photoluminescence (PL) on undoped as well as on Mg-and C-doped GaN grown by molecular beam epitaxy (MBE). We determined the binding energy of the free A-exciton, the residual donorbound exciton and the Mg-acceptor
