Synthesis and photoluminescence studies of one dimensional Sm 2MoO 6 nanofibers derived from electrospinning process

摘要

A combined sol–gel and electrospinning process was employed to synthesize one-dimensional nanofibers of samarium molybdate (Sm2MoO6). X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) and CIE chromaticity studies were used to characterize the resulting samples. XRD studies revealed the formation of crystalline phase of nanofibers on annealing. SEM analyses indicate that the fibers were of uniform size with length of 10–100μm. Due to the efficient energy transfer from host molybdate groups to Sm3+, Sm2MoO6phosphors show their strong characteristic emission on exciting the molybdate group. The emission colors of Sm2MoO6nanofibers are in the orange red region hence suggests its potential applications in fluorescent lamps and field emission displays (FEDs).
