用添加有多壁碳纳米管(MWCNT)的前驱体溶液,通过水热合成法,在260℃条件下制备了一系列YBO3:Eu3+样品.当前驱体溶液的pH值从5到10的范围变化时,所制备的样品表现出丰富的形貌,包括鼓状、片状、六面体状、六角状和花状颗粒,这是由碳纳米管表面接枝官能团与前驱体溶液中不同形式HBO3的协同效应所致.发光测量结果表明pH=9和10的样品的红/橙(R/O)比提高了,表现出更好的色纯度,这归因于晶界或颗粒表面的Eu3+具有较低的局部对称性. A series of YBO3: Eu3 + samples were prepared by hydrothermal synthesis at 260 ° C using a precursor solution added with multi-walled carbon nanotubes (MWCNTs) .The pH of the precursor solution varied from 5 to 10 , The prepared samples showed rich morphology, including drum, sheet, hexahedron, hexagonal and flower-like particles, which is due to the surface of the nanotubes grafted functional groups and precursors solution in different forms of HBO3 synergy The results of the luminescence measurements showed that the samples with pH = 9 and 10 showed an increased red / orange (R / O) ratio, showing better color purity due to the lower Eu3 + on the grain boundaries or on the surface of the particles Local Symmetry.
