摘要
采用静电纺丝法制备了PVP/[Y(NO3)3+Nd(NO3)3]复合纳米带,将PVP/[Y(NO3)3+Nd(NO3)3]复合纳米带在700℃焙烧8h,获得了Y2O3:Nd3+纳米带。使用NH4HF2为氟化剂,经双坩埚法氟化和脱氨后得到YF3:Nd3+纳米带。XRD分析表明,立方相的Y2O3:Nd3+氟化后,得到了正交相的YF3:Nd3+纳米带,其空间群为Abm2;SEM分析表明,Y2O3:Nd3+纳米带和YF3:Nd3+纳米带宽度分布分别为3.7±0.9μm和3.7±0.7μm,厚度分别为360nm和330nm。
PVP/ [Y(NO3)3+Nd(NO3)3] compositenanoribbons were fabricated by electrospinning technique, the compositenanoribbons were calcined at 700℃ for 8h to prepare Y2O3:Nd3^+n anoribbons.YF3:Nd^3+nanoribbons were obtained by fluorination of the relevant Y2O3:Nd^3+nanoribbons followed by deammoniation process via double-crucible method using NH4HF2 as fluorinating agent.XRD analysis indicate that orthorhombic YF3:Nd3^+nanoribbons with space group Abm2 were acquired through fluorination of the cubic Y2O3:Nd^3+nanoribbons.SEM analysis results reveales that the width of Y2O3:Nd3^+nanoribbons and YF3:Nd^3+nanoribbons is 3.7±0.9μm and 3.7±0.7μm, respectively, and the thickness of the two kinds ofnanoribbons is 360nm and 330nm, respectively.
