Biluminescence via Fluorescence and Persistent Phosphorescence in Amorphous Organic Donor(D4)–Acceptor(A) Conjugates and Application in Data Security Protection

Research

Dr. Debdas Ray’s research group (Department of Chemistry) showed biluminescence process via fluorescence and persistent room-temperature phosphorescence in amorphous organic chromophores. These rigid chromophores showed bioluminescence via fluorescence and persistent room-temperature green phosphorescence at ambient conditions. This is the first time that we showed document security protection using those unique systems. We discovered a new way of light-harvesting, and explained the novel mechanism using various spectroscopic techniques. Check the following links:
