Polar c-axis oriented Zn0.75Cd0.25O/ZnO multiple quantum wells (MQWs), grown by pulsed-laser deposition (PLD), emitting in the visible spectral range are reported. By applying a low growth temperature of approximate to 300 degrees C a large Cd content of 0.25 and abrupt interfaces could be achieved using PLD. The emission energy was tuned from the green to the violet spectral range (2.5 eV to 3.1 eV) by tuning the quantum well thickness. It is determined by the quantum confinement effect and the quantum-confined Stark effect. (C) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
