以二茂铁和硅油作为催化剂和原料,利用高温裂解硅油为C,Si,O源,在常压N2和H2混合气氛的化学气相沉积管式炉中制备了大量直径为5—40nm、长数百纳米的非晶SiO2纳米线簇及粒径为100—300nm的C-Si-O实心纳米球.利用透射电子显微镜、扫描电子显微镜对产物形貌进行表征.Fourier红外吸收谱显示出非晶SiO2所具有的474,802和1100cm-1三个特征峰;SiO2纳米线簇的光致发光光谱具有较强440nm蓝光发光峰;而C-Si-O(原子数之比为1.13∶1∶2.35)纳米球具有奇特的红绿蓝(625,540,466nm)三色光致发光谱.
Ferrocene and silicone oil as catalysts and raw materials, the use of high temperature pyrolysis of silicone oil as C, Si, O source, in a mixed atmosphere N2 and H2 chemical vapor deposition tube furnace prepared a large number of diameter 5-40nm, a few 100 nm nanocrystalline nanoclusters and 100 nm-300 nm solid C-Si-O nanospheres were characterized by transmission electron microscopy (SEM) and scanning electron microscopy (SEM) .Fourier infrared absorption spectra showed amorphous SiO2 With the characteristic peaks of 474, 802 and 1100 cm-1. The photoluminescence spectra of SiO2 nanowire clusters have a strong blue emission peak of 440 nm. The C-Si-O (1.13:1: 2.35 atomic ratio) With a strange red, green, blue (625,540,466 nm) three-color photoluminescence spectrum.
