These are only three of several different approaches to hologram authentication, but they have in common the use of the diffraction grating as the vehicle for authentication--respectively measuring its period and orientation, its diffraction spectrum or its physical characteristics.
electron microscope (SEM) and corresponding corrosive X-ray diffraction spectrum (XRD) after immersing for 6 months in carbonation and chloride salt composite pore solution is shown in Figure 3(c).
The X-ray diffraction spectrum of neat PE consists of strong (110) and (200) diffraction peaks indicating the orthorhombic unit cell [31].
A significant observation from the X-ray diffraction spectrums is the evolution of the (002) graphitic nanoparticle peak in the MWCNT and GNP nanocomposites at 26[degrees], indicating the diffraction of the filler particles inside the nanocomposite.
We can see that the main phase is still the hexagonal wurtzite structure for ZnO (JCPDS 36-1451), but it can be clearly observed that there is several weak diffraction peaks except ZnO main phase in the X-ray diffraction spectrum labeled as "a" of sol composite film.
