摘要:
采用水热法制备形貌规整、尺寸均一的β-NaYF4:Yb3+,Er3+微米片,借助X线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等分析技术研究不同反应温度、反应时间对合成产物的物相、形貌和尺寸的影响。结果表明:随着反应温度的升高和反应时间的延长,生成的产物由α-NaYF4纳米颗粒逐渐转变为β-NaYF4微米片。当反应温度为220 ℃、反应时间为24 h时,得到了直径为2.9 μm、厚度为1.3 μm的片状β-NaYF4:Yb3+,Er3+粉体。荧光光谱分析表明,在980 nm激光激发下,β-NaYF4:20%Yb3+,2%Er3+粉体能够发射出绿光(波长521和539 nm)和红光(波长654 nm)。
Abstract:
β-NaYF4:Yb3+,Er3+ hexagonal microplates with remarkably uniform morphology and size were synthesized via a facile hydrothermal route.X-ray diffraction(XRD),scanning electron microscope(SEM), and transmission electron microscope(TEM)were used to characterize the samples.Results showed that the phase of the product was transformed from α-NaYF4 to β-NaYF4,while the morphology changed from nanoparticles to microplates with the increase of reaction temperature and time.Plate-like β-NaYF4:Yb3+,Er3+ microcrystals with 2.9 μm in diameter and 1.3 μm in length were obtained at a holding temperature of 220 ℃ for 24 h.The photoluminescence result indicated that green(521 nm and 539 nm)and red(654 nm)emissions were observed in the upconversion emission spectrum of β-NaYF4:20%Yb3+,2%Er3+ under 980 nm laser diode excitation.
