Özet

In this work photoluminescent properties of the newly synthesized Schiff base; N-(4-dimethylaminophenyl)-3,5-di-t-butyl salicylaldimine (DBS) were investigated in different solvents (dichloromethane (DCM), tetrahydrofuran (THF) and ethanol (EtOH)) and in a polymer matrix (polyvinyl chloride (PVC)) by absorption and emission spectroscopies. Quantum yield (phi(F)), Stoke's shift (Delta lambda(ST); nm) and molar extinction coefficient (epsilon; cm(-1) M-1) of the DBS dye were declared. PVC doped dye was found to exhibit a significant response for Fe3+ in direction of decrease in fluorescence intensity.
