In this paper  we prepared carbon doped nanocrystalline ZnO by pyrolyzed zinc stearate at 250C and 300C respectively. The XRD curves indicate the sample has polycrystalline hexagonal wurtzite structure. The XRD data of the sample prepared at 250C and 300C has a bigger angle shift about 0.05and 0.3respectively. That indicate the structure of the sample has some changes. The EDS indicate the sample contains Zn  O and C. So the XRD shift may attribute to the C. The XPS indicate the C doped in the crystal lattice of ZnO of the sample prepared at 300C  and the sample prepared at 250C may be only a few of C doped in the crystal lattice of ZnO. The PL of the sample prepared at 300C only has a weak ultraviolet emission  which indicates C modified the nanocrystalline ZnO surface as a non-radiative recombination center. In this process C could non-radiatively recombine the carries on the nanocrystallin ZnO surface. The sample prepared at 250C has a strong visible emission at about 530 nm. This emission band could be attributed to oxygen vacancy because C schlepped some oxygen on the nanocrystalline ZnO surface.

The geometrical Modulation Transfer Function (MTF) of CMOS APS (active pixel sensor) is analyzed in this paper. Advanced APS have been designed and fabricated where different pixel shapes such as square  rectangle and L shape  were placed  because the amplifier circuit and other function circuits inter pixel of APS take up some pixel area. MTF is an important figure of merit in focal plane array imaging sensors. Research on analyzing the MTF for the proper pixel shape is currently in progress for a centroidal configuration of a target position. MTF will give us a more complete understanding of the tradeoffs opposed by the different pixel designs and by the signal processing conditions. Based on image sensor sampling and reconstructing model  the MTF expression of any active pixel shape has been deduced in this paper. According to actual pixel shape  three different active area pixels were analyzed  they were square  rectangle  and L shape  their Fill Factor (FF) is 30%  44% and 55%  respectively. Results of simulation experiments indicate that different pixel geometrical characteristics contribute significantly to the figures of their MTF. Different geometrical shape of active sensitive area of pixel and different station in pixel would influence MTF figures. The analysis results are important in designing better APS pixel and more important in analyzing imaging system performance of APS subpixel precision system.
