As to SEM and EDS analysis, there are following errors:
a.) I thiank that the EDS results (Figure 2e and 2f) £¨×¢£ºÍ¼£²£åÊÇ£Å£Ä£ØÆ×·å£¬£²£æÊÇ£Á£çµÄelementa mapping scanl£©are not trusty, because the signal of noise is much higher than that of Ag species. If the authers do the same analysis of other elements (i.g., Au) with the x-ray nenery in the range of 2-7 keV, they will get many similar pictures as shown in Figure 2f. But as we kown, there is no Au in the sample, and the signal results from noise. And I believe that it is difficult to get Ag signal at present content because the surface of Ag/ZnO microspheres is curve not flat (the diameter of microspheres is about 2 micrometers), most of signals can not be dectected due to the position of detector.
b.) EDS can not give the information about Ag nanoparticle locating on the suface or not. Because the electron beam can penetrate several micrometers of sample, which depends on the accerating voltage.
So the conclusions from these two images should be not correct. For example, the sentence of ¡°The precise compositions of the microspheres were confirmed by employing a highly sensitive, energy-dispersive X-ray analyzer (EDX) coupled to the FESEM instrument¡± (page 9, line 47-48) is incorrect. And the author should also provide the Ag content calculated from EDS.
