Abstract
A comparative luminescence and magneto-transmission study is made of donor bound excitons DoX and negatively charged excitons X- in planar doped CdTe/Cd1-xZnxTe quantum wells of 100Å width. As the dopant plane is removed from the well centres to 450Å distance in the barriers, DoX evolves continuously into an X- species weakly localised in random potential fluctuations. The exciton localisation energy in DoX transforms into the second electron's binding energy in X-.
