摘要：
ZnO/Zn1-xMgxO asymmetric quantum barriers on JGS1 quartz glass and Al2O3 substrates were prepared by a pulsed laser deposition (PLD) technique. Microstructure characterization confirmed the designed structure. Because of the design of ZnO/Zn1-xMgxO asymmetric quantum barrier, representative exciton peaks were observed in the optical absorption spectrum at room-temperature. This confirmed that the designed ZnO/Zn1-xMgxO asymmetric quantum barrier structure realized the quantum-binding effect at room-temperature. Moreover, when x = 0:15, the asymmetric quantum barrier structure had optimum performance compared with other x values.
