SnO2:xEu3+(x=0, 1%, 3%, 5%, molar fraction) fibers were synthesized by electrospinning technology. The size of the as-prepared fibers is relatively uniform and the average diameter is about 200 nm with a large draw ratio. The as-prepared Eu3+ doped SnO2 nanofibers have a rutile structure and consist of crystallite grains with an average size of about 10 nm. A slight red shift of the A1g and B2g...
