在室温下，通过快速液固溶法制备了一系列形态均匀、分散性好的高效红色荧光粉K2SiF6:Mn4+纳米颗粒。油酸钾和SiO2球/KMnO4的摩尔比对纳米棒结构的形成起重要作用。当KOH/油酸质量比为2.5:1，SiO2 /KMnO4摩尔比为1:10时，纳米棒的长度为1 ~ 2 μm，宽度为300 ~ 700 nm。在紫外和蓝光激发下，K2SiF6:Mn4+样品显示出强烈的红色发射，与Mn4+的特征谱线相对应。
A series of efficient red phosphor K2SiF6:Mn4+ nanoparticles with uniform morphology and dispersity were successfully prepared through a fast liquid–solid solution route at room temperature. Potassium oleate and SiO2 spheres/KMnO4 molar ratio play an important role in the formation of the nanorod structures. When the KOH/oleic acid quality ratio is about 2.5 : 1 and the SiO2 spheres/KMnO4 molar ratio is about 1 : 10, the length of the nanorods is 1–2 μm and the width is 300–700 nm. Under UV and blue excitation, K2SiF6:Mn4+ samples show strong red emission, corresponding to the characteristic lines of Mn4+.
