Enhanced fluorescence and time resolved fluorescence properties of p-terphenyl crystal grown by selective self seeded vertical Bridgman technique

The fluorescence and fluorescence decay time of a modified Bridgman grown p-terphenyl single crystals have been studied. The fluorescence spectra of selective self seeded vertical Bridgman technique (SSVBT) grown p-terphenyl single crystals exhibit intense peak at 372 nm and a hump at 388 nm. Fluorescence lifetime measured by Time Correlated Single Photon Counting (TCSPC) method for p-terphenyl crystal showed a very short fluorescence decay time (τ) of 3.3 ns.
