摘要:

通过高通量实验方法制备了一系列新型的Ce3+离子掺杂亚磷酸锰(NH4)4[Mn4-xCex(HPO3)6](简称JIS-10∶xCe3+) 无机开放骨架材料. 通过粉末X射线衍射(PXRD)谱图、 扫描电子显微镜(SEM)、 微量元素能谱(EDS)、 X射线光电子能谱(XPS)、 傅里叶变换红外(FTIR)光谱和光致发光(PL)光谱等手段对该材料进行了表征, 并研究了Ce3+离子掺杂浓度、 反应温度和时间对晶体相变和发光性能的影响. 结果表明, 在波长260 nm的光激发下, Ce3+离子在500 nm处有1个绿光发射带而Mn2+离子在590 nm处有1个黄光发射带. 调变JIS-10∶xCe3+材料中Ce3+离子的掺杂浓度发现, 当x=0.06时, 即Ce3+离子的掺杂浓度较低时, 样品的发射颜色为黄绿色, 其CIE坐标为(0.38, 0.48); 当Ce3+离子的掺杂浓度增加时, 绿色发光带的增长快于黄色发光带的增长, 从而调整发射颜色; 在x=1.33时观察到最强的发射, 浓度过高发生浓度猝灭.

Abstract:

A series of novel Ce3+-doped manganese phosphite (NH44[Mn4-xCex(HPO36](JIS-10∶Ce3+) inorganic open-framework materials was prepared under ionothermal conditions. The synthesized compounds were characterized by means of powder X-ray diffraction(PXRD), scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS), X-ray photoelectron spectroscopy(XPS), Fourier transform infrared (FTIR) spectroscopy and photoluminescence(PL) spectroscopy. The influences of Ce3+ doping concentration, reaction temperatures and reaction time on the luminescence property were studied under 260 nm excitation. A green emission band at 500 nm of Ce3+ and a yellow emission band at 590 nm of Mn2+ were observed. At low doping level of 0.06 Ce3+, the phosphor had a yellow-green emission with the CIE coordinate of (0.38, 0.48). The green emission band grew more dramatical than the yellow one when the doping concentration of Ce3+ ion was increased, leading to the tunable color-emission. The excitation competition between Ce3+ and Mn2+, as well as the energy transfer between these species were also studied. The strongest emission was observed at x=1.33, higher than which concentration quenching occurred.
