Sarapulova O. O., Sherstiuk V. P. (Natsionalnyi tekhnichnyi universytet Ukrainy «Kyivskyi politekhnichnyi instytut» (Kyiv, Ukraina) Technological features of application of nanophotonic elements of packaging by screen printing. — 2013. — № 3(41). — pp. 18–26.

The technological parameters that affect the process of producing printed packaging with nanophotonic elements were defined. The factors and parameters of manufacturing coatings based on nanosized zinc oxide with photoluminescent properties for producing active and intelligent (smart) packaging by screen printing were studied. The formation of luminescent coatings by screen printing on polypropylene films was carried out and parameters of deposition process and photoluminescence properties of obtained coatings were investigated. The ways to maximize the integrated luminescence intensity of printed coatings were determined by the method of increasing the thickness of the coatings. The change in the thickness of a layer of printed compositions comprising nanosized zinc oxide was found to affect the ratio of the value of the luminescence peaks at 400 nm and 530 nm, which allows changing this value and therefore manage the color of luminescene of the coatings from blue to green and yellow, which is useful for creating systems with different color of luminescent emission for active and intelligent printed packaging.
