Giant 60-fold enhanced ultraviolet (UV) emission is obtained in Pt nanoparticle-assembled ZnO film. Besides surface plasmons coupling, the conversion of non-radiative recombination into UV emission makes great contributions to the enhancement. It paves a new way in designing high-efficiency UV optoelectronic devices without defect-related energy loss.
在铂纳米颗粒组装的氧化锌薄膜中获得了高达60倍增强的紫外发射。除了表面等离子体激元耦合外,非辐射复合向紫外发射的转变对增强也有很大贡献。这为设计无缺陷相关能量损失的高效紫外光电器件开辟了一条新途径。
