我们提出了一个调查,在近紫外线光化学硅氢加成反应的硅纳米晶体(SI-NCS)晶粒尺寸的影响。的硅纳米晶光致发光(PL)在可见光和近红外区域的大小取决于反应进行了评估使用PL和傅立叶变换。

The PL linewidth is decreased with increasing ammonia flow rate due to the improved uniformity of Si-ncs under high NH3 flow rate condition.
而当氨气流量增加,光激发荧光的线宽会减小,这是因为在高氨气流量下,纳米硅颗粒的均匀度会提升。
In addition, the PL intensity is monotonically increasing with the blue shift of PL wavelength due to the increasing density of small-size Si-ncs.
此外,由于小颗粒纳米硅的密度增加,光激发荧光强度会随着光激发荧光波长的蓝移而递增。
