Abstract
Approaches have been developed for modifying microstructured glass with a hollow core (MG-HC) with polymer and photofluorescent coatings to determine the effect on their optical properties. The layered deposition of cationic polydiallyldimethylammonium chloride (PDDA) and anionic sodium polystyrene sulfate (PSS) was studied. To obtain a photofluorescent coating, the PSS was replaced with AgInS2/ZnS quantum dots (QD), luminescent in red (625nm), orange (606nm), yellow (570nm) and green (556nm).
It is shown that when coating (PDDA/QD) with an increase in the number of bilayers from 1 to 5, the long-wave shift of the MG-HC spectrum is: red QD 10 nm, orange 11 nm, yellow 7 nm, green 8 nm relative to the spectrum of empty MG-HC.
