Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Photonics of cyanine dyes of different ionicity in matrices of halogen-containing derivatives of PEPC polymers were studied. It was shown that in the presence of heavy atoms the intensity of both the fast and delayed fluorescence of the dyes is lower in comparison with the polymer matrix without atoms I or Br. The presence of heavy atoms in the structure of polymers leads to the appearance or enhancement of the phosphorescence of dyes due to an increase in the spin-orbit interaction in the dye molecule and an increase in the rate of singlet-triplet transitions in the presence of a polymer with a large number of heavy atoms.
