摘　　要：以直流溅射方法和真空蒸镀方法结合制备了单组份纳米铝薄膜、纳米金薄膜、纳米2,5-二苯基噁唑(DPO)薄膜和双组份纳米Al/DPO、Au/DPO复合叠层薄膜。利用双势垒伏安特性曲线模拟计算、荧光分光光度计和扫描电镜表征了薄膜样品的电学性质、荧光性质和表面形貌。固态荧光光谱中观察到Au/DPO和Al/DPO叠层结构复合纳米薄膜样品的荧光主峰发生了明显红移。Au/DPO叠层结构复合薄膜样品与单组份DPO纳米薄膜样品的荧光发射光谱相比较,叠层薄膜内相互作用较弱,而Al/DPO叠层结构复合纳米薄膜样品相互作用较强、谱线峰型变化较大,Al的谱线的半高全宽明显增大,推测颗粒内部存在离散的能级结构。Nano-aluminum films,nano gold films,nano 2,5-diphenyloxazole（ DPO） thin films and two-component nano-Al/DPO,Au/DPO composite laminated films were fabricated by DC sputtering method and vacuum deposition method. The electrochemical properties,fluorescence properties and surface morphology of the films were characterized by four-point probe resistance tester,fluorescence spectrophotometer and scanning electron microscopy（ SEM）,respectively.In the solid photoluminescence spectra of the Au/DPO and Al/DPO laminated composite film,a significant red shift of fluorsence emission peak occurred. The interaction within Au/DPO laminated composite films was weaker than in the single-component DPO nanofilm samples,while the Al/DPO laminated composite nano films have strong interaction,and the figure of the spectral line altered tremendously. The full width at half maximum（ FWHW） of Al/DPO composite film is significantly increased. It is presumed that there is a discrete energy level structure in the particles.
