Abstract
The ability of nanoscaled ZnO films to enhance fluorescence was studied. We found that the fluorescence intensities of Cy5, rhodamine 6G, and fluorescein can be enhanced about 10-fold on nanoscaled ZnO films as compared to that on glass substrates. The lifetimes of all samples were measured, and no obvious change in lifetime was observed for dyes on different substrates. The mechanism for the nanoscaled ZnO film enhanced fluorescence appears to be different from that for the metal-fluorophore systems.
摘要
研究了纳米级ZnO薄膜增强荧光的能力。我们发现，与在玻璃基板上相比，Cy5、罗丹明6G和荧光素在纳米级ZnO薄膜上的荧光强度可增强约10倍。测量了所有样品的寿命，未观察到不同基板上染料的寿命有明显变化。纳米级ZnO薄膜增强荧光的机制似乎与金属-荧光团系统的机制不同。
