Energy conversion in 7-(Diethylamino)coumarin doped PMMA fluorescent fibre

The article presents fabrication and spectroscopic characterization of 7-(Diethylamino)coumarin doped polymeric fibre. The poly(methyl methacrylate) (PMMA) was chosen as it assures direct doping possibility and excellent optical properties in fluorescence spectrum of used dye. The fabricated polymer exhibits an intense luminescence (at dye concentration 1.2 × 10−4 mol/l) in the range 505–537 nm (exc. 405 nm). Moreover, he coumarin doped PMMA fibre 600/1200 µm (doped core/cladding) fibre was fabricated and characterized. Presented fluorescence spectrum modification possibility can be used for new optical fibre construction optimization.
