用分子束外延（MBE）生长了由ZnSe势垒分隔的ZnCdSe阱和ZnCdMnSe阱组成的双量子阱（DQW）结构。利用X射线衍射测量和模拟对DQW结构进行了表征。每个阱层的厚度被设计为使得ZnCdMnSe阱的最低能级接近ZnCdSe阱的激发能级。在法拉第几何结构中，利用光致发光（PL）和反射光谱研究了DQWs在8 T外磁场中的光学性质。在具有能量选择性光激发的磁光致发光中，观察到激子从ZnCdMnSe阱向ZnCdSe阱的转移。激子在基态和激发态的能量估计PL激发光谱和反射光谱。
Double quantum well (DQW) structures consisting of a ZnCdSe well and a ZnCdMnSe well separated by a ZnSe barrier are grown with molecular beam epitaxy (MBE). The DQW structures are characterized by using X-ray diffraction measurement and simulation. Thickness of each well layer is designed so that the lowest energy level of ZnCdMnSe well is close to the excited level of the ZnCdSe well. Optical properties of the DQWs are studied with photoluminescence (PL) and reflection spectra in external magnetic fields up to 8 T in the Faraday geometry. Exciton transfer from ZnCdMnSe well to ZnCdSe well is observed in magneto PL with energy selective photoexcitation. Exciton energies in ground and excited states are estimated from PL excitation spectra and reflection spectra.
