Doped zinc oxide colloids can exhibit photoluminescence. In printing industry, it is essential to prepare a feasible printing composition to gain a printable form of zinc oxide nanoparticles, which have good adhesion to the printing substrate. The study is focused on comparison of selected polymers (sodium carboxymethyl cellulose, polyvinylpyrrolidone, and 2-hydroxyethyl cellulose) used as binding agents and its influence on the colour and intensity of ZnO photoluminescence. Furthermore, optimal ratio of the binder : ZnO was studied. The spectral characteristics of zinc oxide layers in (or without) polymeric binders were analysed with UV-Vis spectrophotometry and fluorescence spectrophotometry. The homogeneity of deposited layers was characterised by image analysis using using ImageJ software.Keywords: zinc oxide, binders, photoluminescence, layers, spectra
