heal.abstract	In previous work, we have found for the first time that, besides the known conditions that influence the selectively reflected lightband from cholesteric liquid crystals, the physical sorptive properties of their supports also influence the reflected wavelengths. Thus, it was possible to differentiate metal oxides with different microstructures, chemically from electrolytically prepared metals, sulfated from not sulfated monument surfaces, and to identify the fiber texture of nickel electrodeposits. The reflected wavelength was proportional to the sorptive properties of supports. In the present work, in order to see if the previous findings, especially the quantitative ones, are also valid for other substances, we measured the shift of the wavelength when the liquid crystal mixture covers Zinc oxides prepared by anodic oxidation under different current quantities and by chemical process under different times of immersion in the oxidising bath. It was found that: i. The ageing of the oxides leads to a decrease in the reflected wavelength. ii. The chemically prepared oxides have lower sorptive properties than those electrolytically prepared. iii. The relation between the physical sorptive properties (mgr/m(2) methylene blue) and the shift of the wavelength is similar to the one valid for aluminium oxides.	en
