Abstract
The invention involves encapsulation of phosphorescent molecules in polymeric matrices to prevent phosphorescence quenching. Specifically, polymers containing a significant portion of halogens have been found to be good matrices for encapsulation of phosphorescent molecules to provide strong phosphorescence at ambient conditions. Those encapsulated phosphorescent molecules can find a wide variety of applications for detection of many species, including biological and chemical molecules as well as micro-organisms.
