摘要：

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 100 angstrom width. As the dopant plane is removed from the well centres to 450 angstrom distance in the barriers, D(O)X evolves continuously into an X- species weakly localised in random potential fluctuations. The exciton localisation energy in D(O)X transforms into the second electron's binding energy in X-.
