Abstract
New type of photoluminescence properties of 2,2’:6’,2”-Terpyridine (Terpy) is described. Orthorhombic form of Terpy crystals, which is known to be inherently nonluminous in the visible region, was found to emit strong green light in the presence of traces amount of impurities. Hydroxy-terpyridine, originally included in the Terpy reagent, was found to be the main cause of the green luminescence. Tuning of the luminescent color is possible depending on the dopant species.
