The flower-like Cd-doped ZnO nanostructures were synthesized by hydrothermal method using zinc chloride( ZnCl 2),cadmium chloride( CdCl 2),sodium hydroxide( NaOH) as reactants. Then,the photocatalytic activities of as-grown samples were investigated by photo-degradation of rhodamine B( RhB). The samples were characterized by X-ray diffraction( XRD),scanning electron microscopy( SEM),energy-dispersive X-ray analysis( EDS),photoluminescence( PL) spectroscopy,UV-visible spectroscopy. Experimental results show that with the Cd doping,the morphologies of ZnO changed greatly,and the size of ZnO became smaller. In addition,compared with the undoped ZnO,the absorption edge and the UV emission peak of the Cd-doped ZnO nanoflowers made a red shift clearly. The band gap decreased from 3. 24 eV to 3. 16 eV. Finally,in the photocatalytic experiment,the photocatalytic activity of Cd-doped ZnO was enhanced,and the degradation of rhodamine B( RhB) was up to 98% after the irradiation for 3 h. So the photocatalytic activities of Cd-doped ZnO nanoflowers were higher than that of the undoped ZnO.

We experimentally and theoretically investigate the optical properties of GaN-based photonic crystal surface emitting lasers( PCSELs). We discuss the effects of lattice constant,boundary shape,and lattice type of photonic crystal( PC) on lasing characteristics. The PCSEL structures are fabricated using the metal-organic chemical vapor deposition,the electron beam lithography,and inductively coupled plasma reactive ion etching technique. The optical properties of PCSEL which include the diffraction pattern,emission spectrum,divergence angle and so on are measured by the angular-resolved photoluminescence system. Meanwhile,the plane wave expansion and multiple scattering method( MSM) are used to calculate the band diagram and threshold gain of PCSELs,respectively. The results reveal that the lattice constant plays an important role in selection of lasing mode. Despite the lasing wavelength and linewidth of circular and hexagonal shapes PCSELs are almost the same,the threshold excitation energy density of circular shape PCSEL is 0. 3 mJ /cm2 smaller than that ofhexagonal PCSEL. The PCSEL with honeycomb lattice shows the lower excitation energy density of1. 6 mJ /cm2 and divergence angle of 1. 3°. In case of square lattice,the excitation energy density is twice as large as that of honeycomb lattice. The overall results show that the single-mode emission,low divergence angle,and so on can be produced from GaN-based PCSEL. On the other hand,the numerical results calculated using the MSM are in good agreement with experimental results. The MSM could be a fast and cost-effective approach for predicting the lasing characteristic. We believe that these contributions provide guidance for the development of GaN-based PCSEL.

The stitching interferometer systems with larger relative movement will show a significantly lower positioning accuracy of subapertures. As a consequence a stitching method based on detection of artificial circular mark center to find the necessary translation between two neighborly subapertures is implemented. Firstly,we take coordinates of mark centers as the marks' coordinates by which the translation is computed. Then all the subaperture data are unified into the same reference by homogeneous coordinate transformation and the full aperture phase are stitched by using mechanical system error compensation algorithm. A subaperture stitching process for a 468 mm flat mirror was carried out including surface accuracy tests during the polishing. In this process,subaperture stitching test offered the surface data precisely for polishing,which ensured the surfaceerror converged quickly to a final RMS of 35 nm. The experimental results show that the method relaxes the precision requirement for subaperture location and can get the full aperture phase for large optical element correctly.

The mirror interval and radius of curvature of optical system including three mirrors are often changed due to the impact of space microgravity,which has a greater impact on the back focal length,and causes camera defocus and imaging quality reduction.Through the equivalent Gauss optical system analysis of three-mirror system,back focal length formula can be obtained.By homogeneous coordinate transformation,the reflection mirror rigid-body displacement formula is obtained,and a mirror radius is obtained in the microgravity environment using the least squares fitting algorithm.Finally,by calculating the camera in space microgravity environment,the defocusing amount is 0.04 mm.Results provide a theoretical basis for the design of focusing mechanism.
