英文摘要： As the unique electronic configuration and optical properties, rare-earth ion doping shows advantages in modifying material’s physicochemical properties, which has been demonstrated by its successful application in photocatalysis and solar cells. And it is now one of the research focus in the field of interface materials. However, the fundamental mechanisms how it improves the interface property is still unclear and the obtained device performance still needs to be promoted. This proposed project is aimed to design and synthesize excellent interface materials and develop new effective method for controlling the interface property by rare-earth ion doping, with the purpose to promote device performance. Series n-type and p-type metal oxide interface materials will be doped with rare-earth ions. The influence of the rare-earth ion’s doping concentration, radius and electronic configuration on material’s optoelectronic properties will be studied, to determine the key factors influencing the doping effect. The mechanisms how the interface chemical structure, morphology and electronic properties influence the device performance will be addressed as well. And through these studies, the fundamental theoretic guidance and experimental support for realizing high interface quality and high device performance by rare-earth ion doping will be accomplished.
