The study of si nanostructures is a very active field of research because of their strong room temperature photoluminescence 由于在室温下奈米矽可以产生很强的光激发光,因而引起广泛地研究与讨论。
Excited with 325nm , the emissions bands of 350 ~ 500nm and 640 - 690nm due to the silver clusters and silver nanoparticles respectively 在325nm光激发下,复合膜在350 500nm和640 690nm之间发出荧光,这些发光主要由银簇和银纳米粒子所引起。
The photolumescence ( pl ) spectrum of modified si nanoparticles was changed since the protective agent had modified the surface states , thus altering the light emission characteristics 奈米矽粉的光激发光光谱因保护剂之包覆,改变其发光机制而改变光谱峰。
First , we introduce the seed initiation of sbs model to get the couple equations , which describes the sbs with stokes seeded in fiber 我们首先采用种子光激发模型推导出描述存在stokes种子光下sbs的耦合波方程组,由此分析了sbs的稳态特性,得到了sbs增益因子。
