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

Abstract

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 9 10 -4 mol/l) in the range 505-537 nm (exc. 405 nm). Moreover, he coumarin doped PMMA fibre 600/1200 lm (doped core/cladding) fibre was fabricated and characterized. Presented fluorescence spectrum modification possibility can be used for new optical fibre construction optimization.

Recent Advances in Functional Polymers Containing Coumarin Chromophores

“…Moreover, a loss in total quantum yield was obtained for all co-oligomers in comparison to the vinyl-functional coumarin monomers. The fluorescence of coumarin and its derivatives are used in many different application fields such as in bioimaging [107][108][109][110][111][112], the production of optical fibers by dye doping of PMMA fibers [37], ion detection [113], or damage monitoring in epoxy adhesives under UV light [114]. Another interesting application field of coumarin moieties was shown by Zhang et al, who synthesized polymeric fluorescent brightener based on coumarin for the paper industry.…”

“…Due to the tunable fluorescence and absorbance properties [ 101 ] coumarin molecules are incorporated in numerous application fields such as OLEDs [ 31 , 32 , 33 , 34 ], optical data storages [ 35 , 36 ], or laser dyes [ 37 , 38 ]. Trenor et al and Wagner et al published detailed reviews of coumarin moieties and their photophysical properties some years ago [ 29 , 102 ].…”

“…In the late 1950s, Wheelock and his coworkers showed a shift of the fluorescence band by substitutions on the coumarin structure [ 29 , 30 ]. These properties enable the use of coumarin molecules in numerous different application fields such in organic light emitting diodes (OLEDs) [ 31 , 32 , 33 , 34 ], optical data storages [ 35 , 36 ], laser dyes [ 37 , 38 ], or drug delivery systems [ 39 , 40 , 41 , 42 , 43 , 44 ].…”

Theoretical Investigation of Oxazine 170 Perchlorate Doped Polymeric Optical Fiber Amplifier

“…Their structural properties allow incorporation directly into polymethyl methacrylate (PMMA) which is commonly used in polymer optical fiber technology. The spectroscopic properties of 7-(diethylamino)coumarin, Oxazine 170 Perchlorate, and codoped Perylene-Rhodamine 6G fibers were previously investigated [12][13][14][15]. Optical transmission can be easily obtained for PMMA attenuation optical windows of 465, 525, 565, and 650 nm.…”
