苝/酞菁衍生物薄膜的制备与表征
Preparation and characterization of perylene/phthalocyanine film
-
摘要: 通过真空沉积法制备了苝类和酞菁类衍生物的单、双层薄膜,并对其进行了原子力显微镜形貌表征和傅里叶变换红外光谱、紫外/可见吸收光谱和荧光光谱表征。结果显示:这些薄膜的表面光滑、平整,在450~750 nm有宽而强的吸收,虽然单层薄膜有较强的吸收,但是复合双层薄膜却表现出很强的荧光淬灭。这符合靶丸高压缩内爆对激光烧蚀均匀化的要求。Abstract: The PV, H2Pc, CuPc monolayer or PV/H2Pc, PV/CuPc bilayer films were prepared by vacuum deposition. The films were characterized by AFM, FTIR, UV/Vis and FL. Results showed that the surface of these films was very smooth, they presented strong adsorption in 450~750 nm. Though monolayer film displayed fluorescence, the bilayer film showed strong fluorescence quench. These phenomena agreed with the request of the uniform laser ablation of target in highly compressed implosion.
