Doped high consistence Co can't increase the density of defect levels. ZnO doped Fe is different from doped Mn or Co totaly, the density of photoelectrons anddefect levels aren't reduced obviously. It's probably related the valence of Fe in crystal,general think trivalence of Fe, and form donor levels in ZnO.
Fe掺杂的ZnO完全不同于Mn、Co掺杂,其光生电子密度没有因掺杂出现明显的降低,即缺陷能级密度没有降低,这可能和掺入ZnO所呈现的价态有关,一般认为Fe为三价态,在ZnO中形成施主能级。

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.
