Background technology
Nanofiber is meant the filamentary material that has bidimensional to be in nanoscale on the three dimensions yardstick of material, radial dimension is a nanometer scale usually, and length is then bigger.Because the radial dimension of nanofiber is little of nanometer scale, demonstrate series of characteristics, the most outstanding is that specific area is big, thereby its surface energy and active the increase, and then produce small-size effect, surface or interfacial effect, quantum size effect, macro quanta tunnel effect etc., and therefore show the specificity of a series of chemistry, physics (heat, light, sound, electricity, magnetic etc.) aspect.In the prior art, a lot of methods that prepare nanofiber are arranged, the method for for example reeling off raw silk from cocoons, template synthetic method, split-phase method and self-assembly method etc.In addition, also has arc evaporation, laser high temperature inustion, compound pyrolysismethod.These three kinds of methods in fact all are after at high temperature making compound (or simple substance) evaporation, make nanotube through pyrolysis (or directly condensation), from essence, all belong to the compound steam sedimentation.
The rare earth oxyfluoride phonon energy is low, and higher luminous quantum efficiency is arranged, and has good heat endurance and environmental stability, extensively is used as luminescent material matrix.Mix europium fluorine yittrium oxide (YOF:Eu
3+) be important red fluorescence material.At present, the research of mixing europium fluorine yittrium oxide nano material mainly concentrates on the nano particle aspect.People have adopted presoma pyrolysismethod, solwution method to prepare to mix europium fluorine yittrium oxide nano particle.For example, Zhihua Li, it is presoma that et al adopts the trifluoroacetic acid yttrium, utilizes pyrolysismethod to prepare YOF:Ln
