【摘要】 采用低真空物理气相沉积法制备单组份氰基对称二苯代乙烯(CS)纳米薄膜和罗丹明B(RB)纳米薄膜以及CS/RB叠层纳米薄膜。使用荧光分光光度计、X射线衍射仪(XRD)和扫描电子显微镜(SEM)表征薄膜样品的荧光性质、结构和表面形貌。与粉末晶态样品相比,薄膜样品的荧光发射峰数量变多,发射波长范围拓宽到120 nm。有机小分子的非晶聚集态和纳米叠层结构的的纳米效应导致了样品的荧光性质的变化。更多还原

【Abstract】 Single-component CS and RB nano-films and two-component CS / RB nano-films were fabricated by low vacuum physical vapor deposition( LVPVD) method. Fluorospectro photometer,XRD and SEM were used to characterize the fluorescence,structure and surface morphology of the nano-films. Compared with the powder samples,the fluorescence emission peaks of the nano-films are more,the full widths at half-maximum of the peaks are larger,and the emission wavelength range exceeds 120 nm. The novel fluorescence of the nano-films is caused by the non-crystal state of aggregation of organic low-weight molecules and the effect of the nano layered structure.更多还原
