Light-resistant dyes based on organic and inorganic nanocrystals for optical polymers

摘要

This paper shows that nanocomposites consisting of nanocrystals of organic semiconductors (the dyes Mg phthalocyanine and thioindigo red) and inorganic semiconductors (CdS), introduced in high concentrations into a polymeric matrix (polycarbonate), possess substantially higher photostability than molecular solutions of organic dyes in a polymeric matrix and are therefore promising materials for colored optical filters.
