| 3. | It showed that the porous film had higher transmittance in infrared wavelength region , and the film with metal micro - particles had an optical adsorbing characteristics in the visible light wavelength region 结果表明:多孔氧化铝介质膜在红外波段具有良好的光透过特性,而沉积金属微粒的多孔介质膜在可见光波范围有特殊的光吸收特性,在近红外光波范围具有一定的偏光特性。 |
| 4. | The crystal grain boundary of v2o5 films was melted and disappeared as increasing the deposition temperature , and the crystalline v2o5 films can be obtained by deposition at > 300 . these films showed excellent cathode and anodic electrochromic performance at different wavelength region 而衬底温度升高促进薄膜晶体颗粒长大、熔结,晶粒边界消失,在较高衬底温度( 300 400 ) ,得到连续的结晶性能良好的v _ 2o _ 5薄膜。 |
| 5. | We reported uv - visible - nir light absorption properties of silver colloid , employed as the substrate in sers ( surface - enhanced raman spectra ) , under various conditions . experimental results revealed that the new absorption band in the longer wavelength region was related with chemisorption of molecules on colloidal silver surface 本论文主要进行了与上述相关的研究探讨工作,包括四个部分: 1 、论文通过紫外?可见?近红外吸收光谱研究了作为sers衬底的银胶体系在不同情况下的光吸收特性,结果表明分子加入后在吸收谱长波方向出现新的吸收带,取决于分子在银表面的吸附。 |
| 6. | The dissertation firstly discusses the reflectance of euv and soft x - ray in " multilayer system based on classical electrodynamics and optical characteristics of materials . the nns surface roughness in different spatial frequency range is carefully studied since scattering can seriously reduce the reflectance in euv and soft x - ray wavelength region . we discuss representative model of residual stress in 首先从材料在极紫外、软x射线波段的光学特性出发,讨论了极紫外、软x射线在理想和非理想多层膜系中的反射特性;研究了影响极紫外、软x射线多层膜反射率的表面粗糙度的空间频率范围;重点探讨了多层膜残余应力的典型模型、应力形成机制以及薄膜的形成过程。 |
| 7. | The conclusions are as listed below : compared with absorption of fc16ab in chloroformon , the absorption peak of fcifrab in lb films shifted toward the shorter wavelength region , suggesting that some interaction among molecules due to the close molecular packing such as h - aggregates in the lb films . comparing uv - vis spectra of fc16ab in lb films deposited from cl - subphase with from aqueous subphase , this blue shift phenomenon of absorption demonstrated cl - made the compactness of fc16ab lb films increasing . ft - ir spectra of fc16ab in lb films at different temperature showed that there is a gradual disordering of alkyl chain from 27 ? to 200 ? , but no district phase transition appeared 结论如下:紫外-可见光吸收光谱说明:与fc _ ( 16 ) ab氯仿溶液相比, lb膜的吸收光谱发生了蓝移,这归结于fc _ ( 16 ) ab发生了h -聚集以及抗衡离子可以使fc _ ( 16 ) ab的lb膜排列更紧密;变温红外光谱说明,随着温度升高, fc _ ( 16 ) ab的lb膜中烷基链的有序排布程度减弱,这表明该lb膜热稳定性减弱,但在减弱的过程中没有出安徽人学申请硕士学位论文摘要现相转变。 |
