采用热裂解聚合物前驱体法制备出了具有竹节结构的Si B C N纳米材料。扫描电子显微镜(SEM)和透射电子显微镜(TEM)结果表明样品具有特殊的竹节状(叠杯状)形貌,电子散射能谱(EDX)证实了样品组分为Si、B、C、N。通过微区喇曼光谱仪研究了样品在488nm激光激发下从84～290K的变温发射特性,在490～800nm观察到位于580,620nm附近两个较强发射峰和740nm附近一个弱的发射峰。变温实验说明相应发射峰与材料禁带中形成的杂质能级有关。 Si B C N nanomaterials with bamboo structure were prepared by pyrolysis polymer precursor method. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results show that the sample has a special bamboo-like (stacked cup-like) morphology, electron scattering (EDX) confirmed the sample components of Si, B, C, N . The temperature-dependent emission characteristics of the sample from 84 to 290 K under 488 nm laser excitation were investigated by Raman spectroscopy. Two strong emission peaks at 580 and 620 nm and a weak emission peak near 740 nm were observed at 490-800 nm. The temperature change experiment shows that the corresponding emission peak is related to the impurity level formed in the forbidden band of the material.
