Sarapulova O. O., Sherstiuk V. P. (Natsionalnyi tekhnichnyi universytet Ukrainy «Kyivskyi politekhnichnyi instytut» (Kyiv, Ukraina) The influence of the technological parameters of fixing of nanophotonic printed coverings on their photoluminescent properties. — 2014. — № 4(46). — pp. 21–28.
There was studied the influence of the technological conditions of drying/fixing of coatings based on polyvinylpyrrolidone with nanophotonic components on their photoluminescent properties. It was determined that the impact of convective drying using a temperature range of 40–80 °C increases photoluminescence intensity of obtained nanophotonic layers up to 32 % compared with the same layers that were dried under natural conditions. There was explained the mechanism of the increase of intensity of luminescences of layers by ZnO nanocrystals. It was found that the maximum possible increase in luminescence intensity occurs at a temperature of 60 °C. Based on experimental data there were determined the optimal settings of the process of drying/fixing nanophotonic printed layers of different thicknesses to obtain the highest possible increase in the photoluminescence intensity of printed nanophotonic elements that can be used to provide the functionality of smart packing and to protect printing products against forgery.
