Enhanced luminescence of Ca2MgSi2O7:Eu2+ fibers by sol–gel assisted electrospinning
چکیده انگلیسی

Ca2MgSi2O7:Eu2+ fibers were successfully fabricated by a sol–gel assisted electrospinning and subsequently calcination procedure. The phase formation, morphology and the luminescent properties of the fibers were determined. Two strong Eu2+ emission centers were observed in the emission spectrum, which were ascribed to two types of cation sites existing in the Ca2MgSi2O7 lattice, respectively. The Ca2MgSi2O7:Eu2+ fibers reveal bright green-emitting under the excitation of near UV and blue lights. Compared with the powder sample, the luminescent fibers had average grain sizes less than 1 μm and could be synthesized at a relatively lower temperature. The green luminescence in the luminescent fibers was also greatly enhanced. The intensity of the major peak at 539 nm was stronger and had longer average decay time than that at 466 nm. The Ca2MgSi2O7:Eu2+ fibers are expected to be used for optical detectors, bio-labeling and full-color display devices.
